Installation of interior doors types of hinges. How to weld hinges on a door made of metal. Marking and cutting out seats

02.06.2019

The safety of the owners depends on the correct choice of entrance doors, and further comfort and coziness in the house depends on the successful selection of interior doors. But it is important not only the canvas itself, but also the high-quality installation of fasteners. Using the most suitable canopy guarantees a long service life for the entire door.

Varieties of canopies

A variety of door hinges allows you to choose which side the door will open. Therefore, in order not to regret the decision made after its installation, it is important to decide in advance on the type and principle of operation of the loops.

Loops are a fairly simple device that allows you to do all the work with your own hands.

Loop butterfly

They are the most practical for interior doors. Butterfly loops got their name because of their characteristic shape - when open, they resemble butterfly wings. When folded, the canopy is one card thick. This is achieved thanks to a special shape ─ when closing, one “wing” of the butterfly is accurately marked in the cutout of the second.

When installing such hinges, it is very important to choose suitable screws. Since the two parts of the "wings" of the butterfly will be in direct contact with the tree, you should use such self-tapping screws, the hat of which will be ideally hidden in a special loop groove. With the right choice, the sash will close well and there will be no additional difficulties during its use.

Simple mortise

This is the most widely known type of canopy. It is used in almost every home. It consists of two parts and is fixed with ordinary wood screws.

Since doors can be of various sizes, such hinges must also meet the requirements for use.

Overhead

Structurally, they are not much different from the previous ones, but there are still some differences. The main nuance that should be considered when installing these canopies is the method of installation. If the previous version is attached simply to the end of the door, then for this type of hinges it is necessary to make special recesses (embed). This is necessary in order to hide the mounting plates and make a smaller gap between the door frame and the jamb.

Installation of overhead loops

This work is not difficult, due to the simplicity of the design of the loops. Outwardly, they are quite simple: two parts (“father-mother”) are connected into one, which facilitates installation. In order to evenly and correctly fix the door on the canopies, you first need to screw the hinges to the door frame. Such an installation must be carried out extremely accurately, otherwise curvature will appear as a result, and they will not be able to open normally.

Next, you should correctly install the door on the substrate of the desired height and at a slight angle relative to the overhead canopies. Then you need to open and lean it against the end of the frame. It is important to accurately fix the position of the door. You can do this with an ordinary plumb line. After the final adjustment, you can fix it with self-tapping screws.

They need to be tightened strongly, but carefully so as not to disturb the structure of the tree.

Universal loops are quite simple in design. Their main difference is that they are non-detachable. Often they are small in size, which undoubtedly gives them a certain elegance. Their installation will not take much time, because it does not require any additional work. Such hinges have a small thickness, so even with the door closed, the gap between it and the opening lining is small. When using universal canopies, the beauty of the doorway and the invisibility of the joint are preserved.

How to install hinges correctly

No matter how beautiful and attractive the door may be, improperly installed hinges will spoil not only the impression. If it does not close ─ the benefit will be small. Therefore, at the markup stage, it is important to take the work seriously. Many of this work is done either in a hurry or hastily. But most often, after that, you have to twist the canopies many times and spoil the wood of the door. To avoid this, you need to know some of the nuances regarding the installation of loops.

Number of loops. It all depends on the size and weight of the installed door. Since its weight can vary from 2.5 to 8 kg, the number of canopies will also be different. The standard height of interior doors does not exceed 2.3 m, the most correct decision would be to install two canopies.

However, there are designs that have large dimensions. In this case, you need to increase the number of loops.

If there are three of them, you can combine them as follows:

Two on the edges of the door (15-20 cm from the edge), and one in the center;
Two at the top (the second is 10 cm below the first);
Two at the bottom (the second is 10 cm higher than the last).

Markup is recommended to be carried out in several stages. To facilitate the work, it is best to divide the hinges into two parts ─ upper and lower. The second canopy element (the one with the stud) must be mounted on the door frame, while the first (with a special groove for the stud) will be mounted on the door frame.

Getting directly to the markup, it is advisable to arm yourself with a sharp pencil. In order to make the markings on the door frame as correctly as possible with your own hands, you can simply attach one of the parts of the canopy in the place where it will be attached. Then you should circle it along the contour with a pencil.

It is important to do this as close to the edges of the loops as possible. Since special recesses are often cut out for them on the frame and on the door frame, the further operation of the interior door will depend on the accuracy and quality of the markings.

After the markings are made on the frame, you can proceed to the door frame. In order to choose the right place in height for the second part of the canopy (the one with the hairpin), you can resort to one trick: put a plank under the door, the width of which corresponds to the height of the desired gap between the door and the floor; after which you need to transfer the dimensions of the canopy to the door jamb so that they coincide with the first part of the hinges screwed to the frame.

Inserting hinges into interior doors

To make the canopies look beautiful, they can be cut into a tree ─ both the door frame and the door itself. Many choose to do this work with their own hands, because there is nothing complicated in it. It will require several tools:

Chisel;
Hammer;
Pencil;

Before starting, it is important to correctly and accurately circle the canopy from all sides. Further, according to these measurements, you need to make a recess, with a depth equal to the thickness of the loop material.

The whole process can be seen in the following video:

In order to qualitatively and correctly perform the grooves, it is important not to rush and approach this matter responsibly. It is necessary to perform exactly such a depth that will ideally correspond to the thickness of the plate. After all, if the groove is deeper, the protrusions of the frame will catch on and the opening and closing will not be smooth. And vice versa ─ if it is too small, then there simply will not be room for loops.

So, having more complete knowledge in the matter of choosing loops, you can make a more confident choice. It is worth remembering that no matter how high-quality the hinges are, timely lubrication of the rotation elements will only extend their service life. Moreover, the installation and insertion of canopies will serve as a good experience and will come in handy in the future.

When buying doors, hinges are usually installed. But if the structure was purchased disassembled or only the door leaf is being replaced, door hinges are being installed. It can be done correctly with your own hands, without spending money on the services of a specialist. The main thing is to carefully follow the rules of the tie-in, or problems may arise during operation: creaking, mashing, jamming.

Common Varieties

Before buying, it is better to study the product range and get acquainted with the design features and appearance in order to properly install the awnings.

By location

In the direction of opening the door canopies are:

Left-sided.
Right-sided.
Universal.

To correctly determine what type of hinges you need, you need to face the opening from the side into which the door opens (toward yourself). If it goes to the left, left-handed loops are needed, to the right - right-handed ones.

By type of material

Loops are:

From brass - canopies are plastic: chrome-plated and polished.
Brass - based on an alloy of different materials, on top they are covered with a decorative coating imitating bronze, gold, silver.
Made of steel - the most reliable type, not amenable to erasure.

In appearance and equipment

The most common models:

Card (straight) - there are plates on the sides. A good option to hang interior doors.
Corner canopies - designed for swing doors, have the shape of an angle.
Screwed - instead of plates, they have pins mounted on the axis, designed for light door models.
Hidden - installed on expensive front doors. The hinge is recessed into the structure.
Italian hinges are very similar to ordinary furniture hinges.

According to the method of fastening

By installation type:

Overhead canopies - they can be placed on top of the canvas and the box.
Mortise - special recesses are made for them.
Screwed - screwed onto the pins of the mechanism.

Before buying, you need to consider the following points:

The weight of the door - usually two hinges are enough. But if you hang the canvas heavier than the standard one, or there are doubts about the reliability of the hinges, it is better to install three.
To avoid squeaking, you need to install special bearings for the hinges.
Determine the position of the loops: left-handed, right-handed.

Butterfly loops: features

- consignment note, card model.

Does not require tapping due to a special design - it does not consist of two plates, but is a solid plate divided into two parts, which, when closed, enter into each other, without the formation of gaps.

The advantage of the canopy "butterfly":

Easy installation.

Disadvantages of a canopy "butterfly":

The door does not come off the hinges.
Over time, distortions are possible.
Used for lightweight fabrics.
The canvas must be perfectly flat.

Mounting tool:

Screwdriver.
Awl.
Drill.
Roulette.
Pencil.
Self-tapping screws.

Do-it-yourself installation of butterfly door hinges:

Make indents from the edge of the canvas from above, from below by 20 cm.
Attach the plate to the end, mark the holes for the screws.
Drill.
Raise and attach the door to the box, duplicate the location
Screw on the loops.
Raise and hang the canvas.

If a gap has formed between the box and the plate, it is necessary to put a gasket under the butterfly-type loop with your own hands.

Hinges on a metal door

They perform the same functions as interior ones, but are not interchangeable, because they need to be welded.

Types of canopies for metal doors:

Hinges with bearing - thanks to it, structures can withstand doors of greater weight.

There are: cylindrical canopies (it is necessary to weld to the plates that provide a gap between the loop and the canvas) and drop-shaped (the shape itself provides a gap).

Hidden (internal) loops - protection against cutting, protection against atmospheric phenomena. Minus - the canvas does not open completely. There are two types: lamellar (plates connected with pins, for light doors) and cylinder (withstand heavy doors).

Do-it-yourself installation of hinges with a bearing:

Place the canvas in the box, observing the gaps.
Treat the canopies with grease (so that the ball does not stick when welding).
Put the canopy - the hinge pin is directed upwards, adjust the gap.
Weld with electric welding.

Do-it-yourself installation algorithm for hidden canopies:

Preparation of openings for canopies: rectangular recesses in the canvas and box.
Weld into the opening of the box.
Weld to the canvas.

In everyday life, canopies with a bearing are most often used, because of the ease of installation.

Door markings

You will need:

Pencil.
Ruler (long)

Do-it-yourself marking algorithm:

Determine the opening (left-handed or right-handed).
Measure from the top and bottom of the canvas 20 cm, make notes.
Attach loops to the marks (the top of the plate on the mark), circle, mark the points for fastening the screws. The rod should not touch the canvas - so that the door opens and closes freely.
If there are knots or chips at the calculated place, the loop should be placed a couple of centimeters lower.
Collect box.
Make marks in the same way, observing the gap between the box and the canvas (2-3 mm).
If the canvas is made of solid wood, or is weighted, you need to put one more loop (a little closer to the top).

How to make a do-it-yourself tie-in

Required tools:

Screwdriver.
Hammer.
Chisel.
Drill and drills.
Screwdriver.
Cutter.
Awl.

How to embed hinges in the door - independently and correctly. Insertion algorithm:

If the canvas is from an array, you must choose a place without knots and chips. An ordinary canvas - make indents of 15-20 cm from the bottom and top. A loop will begin from this point.
Mark the edges of the attachment with a pencil or screw it in temporarily to make cuts with a cutter or chisel (light hammer blows)
You need to knock out the platform under the loop inward so that the edges remain even.

Check the depth of the recess: attach a loop to the recess, put a ruler on top - if it does not stick out, the depth is sufficient. If it protrudes, the gap between the box and the canvas will be large. You need to increase the depth. If the hinge is recessed, the door will press the box. A gasket is required (e.g. cardboard).
Assemble the door frame, lift and attach the canvas, making an indent of 2 mm on top, duplicate the markings.
The hinges cut in, as in the canvas.
Raise and hang the canvas.

Hidden hinges: installation features

This mechanism is used for hidden doors - the door merges with the wall.

Able to withstand canvases of different weights: cheaper - 40 kg, more expensive - 200 kg. When buying, you should proceed from the weight for which the hinges are designed.

Loops can be placed in a canvas of the following materials:

Wood.
Aluminum.
Steel.

The location of the hidden loops: the end of the canvas.

If ordinary loops are installed in the amount of two pieces, then three hidden ones are needed - for reliability.

More about installing loops on the video:

If the installation of hidden loops has taken place, some models are adjusted with a hex key:

Horizontal adjustment: alignment of the sash with a screw, relative to the jamb.
Vertical: adjustment of the gap canvas-floor, the top of the canvas-top of the frame with a vertical screw.
Clamp - uniform fit of the leaf to the door frame with an adjusting eccentric.

As a result, hidden hinges are used on doors from the upper price segment, so they are made of quality materials, which is reflected in the total cost of the kit. There are no particular difficulties in their self-installation and adjustment, but before that you need to carefully study the instructions in order to understand all the nuances of the process.

Very often, poor-quality fittings or their not entirely correct installation lead to such door defects as creaking, deformation of the door leaf and spontaneous opening of the door. Often the installation of doors is carried out by the company that installs the doors, but when buying a collapsible model, you often have to do the installation yourself. Or just sometimes the moment comes when it's time to put new fasteners.

Hinge sizes are different, so today you can install anything that you think fits your door leaf. The choice is really great. If we talk about the material, then today you can buy steel, brass, brass-plated hinges.

Steel hinges are a mount that does not grind, which means it will last a long time. Brass hinges are the most popular, everything is simple - brass is easy to process, chrome, polish. For the manufacture of brass compositions, different alloys are used, and on top they are covered with chrome, bronze, gold.

The weight of the fittings on which the door is to be mounted is also very important. Sometimes a couple of loops are not enough to do everything right. Then the number of hinges increases to three if the door is heavy and massive. And if the products are also equipped with bearings, then they will not creak even under heavy load.

Which hinges are better to put on interior doors

So, the loops differ in size, also in the number of holes, in the way of opening, in the mechanism of action, etc. Two card hinges will not be able to hold a heavy massive door, in this case there must be heavy welded elements. Plastic doors use some canopies, it is customary to install wooden ones on others, etc.

Types of door hinges:

Overhead- they do not need any grooves or recesses;
Mortise- are installed in a certain recess, which is made both in the canvas and in the box;
screwed- they have special screws that are built into the platform;
corner- these are models that are used to install the pendulum system.

Also, the loops can be left, respectively, right, and it is also worth highlighting the popular range of universal loops. To determine what kind of loops you need, you can do the following. You need to stand facing the doorway, evaluate where exactly the canvas opens, the door, remember, can only open forward in the direction of movement (if this is correct).

Precise insertion of hinges in interior doors

Marking is the first step in installing loops. You can mark the attachment point as follows: retreat 20 cm from the top and bottom of the door leaf, the initial lines are marked with a pencil. Then the loops are applied to the marks made, the contour is outlined, the points at the attachment points are indicated.

To ensure the free movement of fasteners, you need to make sure that the rods do not touch the door leaf. Inspect the location of future fittings - there should be no defects, knots, etc. at the tie-in points. Otherwise, self-tapping screws screwed into these places can cause distortions or even split the door.

After that, the door block is assembled, and in the same way it is necessary to make markings on the box, observing the gaps of 2-3 mm between the canvas and the box. It is convenient to do this with an uninstalled door. If the door leaf is heavy, you need to embed a third hinge. Then the insert is not made in the middle, but with some offset to the upper loop. This will regulate the load on the fittings.

Installation of concealed door hinges

Very often today, the so-called hidden door hinge models are used today. They do not weigh down the facade of the doors, in addition, they are easy to care for. And also the design features of such models increase the class of such a category as burglary resistance, and if the front door is an important point.

How to install invisible hinges:

The position of the parts is outlined;
An electric milling cutter makes a recess under the mechanism;
With a chisel, a layer of material is removed in place under the fittings;
Loops are disconnected;
The larger element is inserted into the door frame, fixed with self-tapping screws;
The smaller part is fixed in the canvas;
Both parts of the hinges must be connected and the fixing screw must be tightened.

Sometimes decorative inserts are installed over the mounts. And if you need to adjust the hidden loops, this is done only in the open position. First, the decorative trims are removed, then the screw is tightened with a hex key. The design features are such that the position of the door can be adjusted in three planes.

How to check the fit

To check if the loop is set correctly, you need to take a ruler and press the loop with it. If the hinge is cut in the wrong way, and it protrudes too much, there will be a serious gap between it and the door leaf, and on the other hand, the opening is not enough for the door to close. To fix this, you need to unscrew the hinges and plant them deeper.

And if the hinge, on the contrary, is set very deep, the door will press the box and will pull the hinges. And the way out is this: a stand-gasket of the required thickness is cut out of thick cardboard, it is placed under the loop so that it falls into place. In order not to embed-cut endless loops, you need to do the markup correctly.

How to embed hinges in an interior door (video)

Mounting hinges are made for wooden, and for metal, and for plastic doors. Choose high-quality fittings, inspect it when buying for defects, and mount fasteners according to the rules, with accurate markings.

Good results!

Every home craftsman should know how to install hinges on a door. The quality functioning of interior structures directly depends on the correct installation of these small parts.

So many of us, when choosing, do not even think about how important loops are for such structures. We are sure that the design of the door leaf and the reliability of the box being purchased are much more important, and everything else is trifles. This approach to choosing a door is wrong. A canvas without well-chosen canopies will be just a blank. There is no sense from her. Only after installing the hinges, the door turns into a functional structure.

Hinges for interior doors

There are five types of door canopies that are most commonly used these days. Before you install the hinges on the interior door with your own hands, you need to understand their design. The specificity of the latter determines the features of the installation of canopies. The following are the common types of loops:

Card (otherwise they are called direct). The simplest canopies, equipped with special plates on the sides.
Corner. In fact, they are the same card loops, from which they differ only in the shape of the (angular) plates. Such canopies are usually placed on interior doors of a pendulum design.
Hidden. Hinges mounted on expensive products. Hidden awnings have a special hinge that is recessed into the door leaf.
Screwed. These products do not have plates. Instead, there are pins on the swivel axle. Screw-in awnings are ideal for light curtains.
Italian. They have a hinge with a special design. Such hinges are usually mounted on European-made doors.

Canopies for interior structures are also divided into universal, left- and right-handed. The first of these can be placed on either side of the canvas. According to the method of installation, the hinges are divided into mortise (they form a single surface with the door, as they are mounted in recesses prepared in advance), overhead (placed directly on top of the door structure) and screw-in (they are screwed in with pins).

We begin to figure out how to properly install the various types of hinged products of interest to us. The very first step is marking the door leaf. You need to step back from the top and bottom of the door by 0.2 m and mark the initial lines (use a simple pencil). After that, apply the hinges to the completed outlines (be sure to take into account the direction in which the door structure will open), circle their contour. And then put the appropriate marks at the attachment points.

Fitting and installation of loops

At this stage, you should carefully examine the condition of the canvas. In areas where canopies will be installed, there should be no defects, in particular knots or cracks. If during installation you begin to screw fasteners into problem areas, there is a high probability that the door will crack or warp. If defects are found in the marked area, re-mark so that the attachment points of the canopies are a couple of centimeters away from cracks and knots.

Now you can assemble the door block and mark the mounting points of the hinges already on the box. In this case, it is necessary to maintain small (literally 2–3 mm) gaps between the door leaf and the door frame. This procedure is easiest to perform before the door structure is mounted in its proper place. If you have already installed the door, fix it (as tightly as possible) with wooden wedges in the opening.

When the mass of the interior door is large enough, you need to hang it not on two, but on three hinges. At the same time, the latter should not be cut in the middle of the canvas, as many believe, but with some offset towards the canopy located on top. In this case, you will be able to correctly adjust the load that affects the fittings used. The third hinge must be installed if the door has dimensions larger than standard (50 mm thick, 200 cm high, 80 cm wide).

Card-type hinges (angular and simple) are mounted very easily. Moreover, this operation can be performed in two ways. The first is suitable for canopies, the two parts of which are characterized by different shapes. Hinges of this type are one in one when closing the interior door. Due to this, they are mounted directly on the surface of the canvas.

Card loop

To install such canopies, you will need an electric drill. There are two nuances here:

If the hinges are placed on a heavy door, it is necessary to pre-drill holes in it, only after that you can start screwing in the screws.
Hardware can be screwed in immediately, without first making holes for them, if you are dealing with lightweight structures made of plastic or wood-fiber material.

The second installation technique assumes that you slightly sink the canopies into the door. In this case, when closing, they will never stop the canvas (when using the first installation method, this situation occurs quite often).

Notches for loops are recommended to be made with a regular chisel. Just cut off the material on the loot and on the door itself to the depth of the mounted canopy. And then attach the latter to the site of its installation and fix with fasteners. Mount and fix corner products in the same way. Place one half of them on the end of the door leaf, the second on the loot.

Modern models of interior doors, as a rule, are equipped with better and more innovative fittings. Similar designs need to be mounted on hidden canopies. Such hinges are much easier to care for, they rarely need repair, as they have a high level of operational reliability. Yes, and a purely outwardly installed covert canopy makes the appearance of the door more attractive, without burdening the canvas with well-marked hinged elements.

Hidden Loop Example

For the correct installation of hidden loops, an electric router is required. Without it, you will not be able to perform the operation yourself. The installation itself, in the presence of such a tool, is carried out according to the following scheme:

Mark the attachment points of the canopies according to the algorithm described in detail above.
With an electric cutter, cut out recesses for the loops. And then you additionally process these areas with a chisel.
Disassemble the hidden canopy into two parts. There is a very important point here. The elements of the loops have different geometric dimensions. You need to install a part with large parameters in the door frame, and a smaller part in the door leaf. And nothing else!
Secure most of the mechanism with self-tapping screws.
Connect the mounted elements into a single structure and with some effort, but very carefully tighten the mounting screw.

Screw-type canopies are most often used to install feigned interior structures. It is very easy to distinguish such loops from ordinary card loops. The first ones have special threaded pins on the sides. It is they who allow the installation of canopies. We repeat that screwed products cannot be placed on doors with a lot of weight. Italian awnings are mounted in the same way as standard card awnings. But with one feature. They are placed below and above the door leaf, and not at the ends, as is the case with card products. We hope that now you will be able to install hinges of any type on your interior door structures without the help of specialists. Good luck!

If you decide to purchase new beautiful doors, pay attention to whether the kit includes the door leaf, frame, handle and lock, door hinges. If the design is sold without hinges, you have to choose and install them on the door yourself. This process must be taken responsibly, as unsuitable fittings can spoil the appearance of the door, and improper installation can lead to skew of the canvas and problems during operation.

Today, there are many types of door hinges, which differ in appearance, fastening method and functionality.

Types of hinges depending on the design and installation method

Among the variety of hinges for entrance and interior doors, several types can be distinguished.

Overhead hinges

Such canopies are also called loops without tie-in. They are installed directly on the surface of the door leaf, without deepening the seat under the wings of the hinges. They are attached to the door leaf and the frame with wood screws.

simplicity and ease of installation;
the possibility of self-assembly without special skills and tools.

the design of the canopies does not allow, if necessary, to remove the doors without unscrewing the screws;
they can not hang doors that have a lot of weight.

Recently, overhead butterfly loops have been especially popular - these are loops without a tie-in, the elegant shape of which resembles a butterfly wing. When folding, one part of the structure is embedded in another, ensuring a minimum thickness.

Mortise

In appearance, they resemble invoices, but differ from them in the method of installation: for the installation of mortise hinges, cuts are made at the end of the door leaf and frame. The recesses must correspond to the thickness and dimensions of the wings of the structure.

relative ease of installation;
low price.

The downside is the need to cut recesses in parts of the door structure.

Overhead and mortise door hinges are detachable and universal. Universal designs are considered more reliable, as they have a rigid assembly that prevents sagging and loosening of doors.

corner

Not flat wings-plates, but corners are attached to the axial rod of such canopies. They are installed on interior doors in the same way as mortise ones.

The advantages of such hinges can be called the convenience of placement and the dense vestibule of the door due to the angular shape. Minus - visibility against the background of the door structure.

Hidden

They differ from all other designs, as they are installed in pre-prepared recesses, sawn out in the box and door leaf.

inconspicuous fasteners do not violate the aesthetic appearance of the door structure;
make it possible to adjust the position of the door;
such loops cannot be cut.

The only drawback is the complexity of installation; without certain skills, you are unlikely to be able to correctly install such loops.

screw-in

In such door hinges, instead of wings, pins are located on the axis, screwed into the door leaf and box. The device has a number of models with a different number of threaded pins designed for different door weights.

universality (no need to select right and left loops);
stealth.

on such hinges you can hang only doors with euro-porch;
when used on structures made of low-grade brittle material, they can lead to cracking, chipping.

The choice of canopies according to the material of manufacture

Depending on the material, the loops are divided into three types:

Steel - are considered the most reliable and durable. In its pure form, they are not very attractive, chrome-plated models look more aesthetically pleasing.
Brass - beautiful in appearance, but less durable due to the plasticity of the material. Can be polished or chrome plated.
Brass-plated - made of zinc or steel alloys, have a layer of brass on top, often additionally coated with enamel or compositions that imitate noble metals.

A few words about butterflies

If you decide to stay on the easiest version of the hinges to install, it is advisable to purchase them in specialized stores. When buying, make sure that the sides of the structure fold correctly, otherwise bumps will form during installation, and the door will not fit well or begin to spring.

Interior doors, according to their characteristics, should be suitable for the installation of overhead butterfly hinges on them. Installation of this type of canopies is carried out only on the places of the door leaf intended for this purpose, suitable for tightening self-tapping screws.

In connection with the overhead method of installation and the properties of the design, "butterfly" awnings are intended mainly for light interior doors. Due to their aesthetic shape, clean installation, which takes place without disturbing the decorative finish of the door leaf, they are excellent for hanging modern doors with an original design.

Consider the installation sequence of popular butterfly hinges on the door, which are mounted without cutting into the door leaf and frame.

An important advantage of butterfly loops is the exceptional ease of installation: you do not need the ability to handle carpentry tools.

First, the primary marking of the location of the loop is made. To do this, you need to measure the distance from the upper and lower edges of the door leaf - it must be at least 200 mm. Attach the inside of the loop to the place of its future attachment to the canvas and circle the part with a pencil.

Note! The hinges are placed with hinges to the front of the door.

While holding the loop, mark the points for drilling holes for self-tapping screws with an awl or a thin drill, the diameter of which should not exceed the diameter of the axis of the self-tapping screw.
Screw the inside of each hinge to the door leaf with self-tapping screws.
Install the canvas in the box, observing the required gap, make sure that the top and bottom ends are located correctly (strictly horizontally), and fix it with wedges.
Mark the location of the outer part of the hinge, remove the wedges and screw the top hinge to the box.

Important! To avoid breakage or distortion of the hinge, the door must be supported until the lower canopy is installed.
