Plastic products have firmly entered our lives and now not only small things are made from it, but also furniture and interior items. Plastic doors are not a new product for a long time, and now interior plastic doors have also become very popular. This is the first time many repairmen have to work with plastic hinges, and therefore they do not always know how best to select and install them. The following material will show you the nuances of choosing hinges for plastic doors. Read more about hinges for PVC doors.
What are hinges for plastic doors
Hinges are one of the most important components for a plastic door. The performance characteristics of the entire structure depend on the quality and reliability of the elements. Depending on the weight of the sash, there can be two or three hinges; they can be installed for both left and right opening.
The plastic loop consists of the following elements:
Hinges are one of the most important components for a plastic door; the performance characteristics of the entire structure depend on the quality and reliability of the elements.
- leaf part with a metal tab, which is attached to the door leaf;
- frame part with pins for fastening to the frame;
- a spacer sleeve made of particularly durable material and designed to connect the sash and frame;
- fasteners.
For a standard plastic door, it is recommended to use three hinges: two are mounted at the top of the sash, one at the bottom.
How to choose hinges for plastic doors
When choosing hinges for PVC doors, take into account the following parameters:
- permissible load on the product: The characteristic is usually indicated in the passport or other accompanying document for the fittings. You can also focus on the width of the profile: on a narrow profile, hinges are installed with a design load of up to 80 kg, on a wide one - up to 160 kg;
- side of the door opening: hinges are left and right. To determine the opening direction, you need to stand facing the door so that you open it towards yourself. If it is more convenient to do this with the right hand, then right loops are needed, if with the left hand, then left ones;
- profile width: for narrow frames use fittings with a width of no more than 90 mm, for wide frames – up to 110 mm;
- adjustability: it is best if the hinge allows you to adjust the position of the sash in three planes. In this case, using a simple screwdriver, you can change the canopy vertically, horizontally, and also adjust the degree of pressure for comfortable opening.
How to adjust plastic doors: identifying damage
After several years of operation, plastic balcony and entrance doors let cold air through, do not fit tightly, and jam when closing and opening. Self-adjustment eliminates malfunctions. Before starting repairs, determine the nature of the defect.

The canvas clings to the box and creaks. The door opens and closes with interference, friction is noticeable. Adjusting plastic doors eliminates the defect: if it is not corrected in time, the profile will be damaged.
The doors sagged. Failure is detected during inspection of the structure. If a gap forms in the upper part of the door, and the lower part touches the threshold, this means that the canvas is sagging.
The handle wobbles or jams. In the first case, the cause of the defect is inaccurate operation, in the second - wear of the lock core, clogging or sagging of the door leaf.
The 3-way mechanism jams. The reason may be contamination of the part or its wear.
Hinges for plastic doors
Modern plastic doors, which have received wide consumer recognition, require appropriate modern fittings, including hinges. Hinges for plastic doors are a structurally simple device, usually consisting of two parts - frame and leaf, which are attached to the frame and leaf of the door structure. Wear-resistant steel pins and bushings are used to connect them. Some features of fastening to the frame and sash depend on the profile used.
The range of hinges currently offered is very wide and varied and can satisfy any requests of door manufacturers and their consumers. In particular, these are overhead, corner, universal, hidden installation, etc. Hinges for PVC doors can be of different sizes and colors, their parts are made of different materials: steel, bronze, aluminum, various alloys, plastic, Teflon.
The choice of hinges for a plastic door is determined by:
- purpose and type of door (external entrance, vestibule, apartment entrance, interior, bathroom, toilet, etc.);
- profile width;
- the material from which the canvas and frame are made (wood, steel, aluminum alloy, plastic);
- dimensions and weight of the door leaf;
- opening direction - inward or outward, left or right;
- the expected need to regulate the position of the sash.
The reliability of their operation and durability depend on the correct selection and correct installation of hinges for PVC doors. These parameters directly depend on the loads perceived by the hinges, the operating mode of the door, the frequency of opening and closing, external conditions, etc. In some cases, especially for large and heavy doors, it is necessary to increase the number of hinges to three or even four, and two of them should be located closer to the top.
To facilitate the high-quality performance of installation of hinges, manufacturers offer installation templates for use, which eliminate the need for precise measurements and marking of installation sites.
Door hinges for plastic doors not only provide reliable fastening of the sash to the frame and easy opening of the door, but also allow, if necessary, to adjust the position of the sash relative to the frame in three directions with a tight fit - clamping, without distortions or jamming. Correct selection and installation of hinges, their proper adjustment is the key to reliable operation of the door and a long service life.
Adjustment
Metal-plastic balcony windows or doors often have to be repaired. Sagging is the root cause of hinge failure. Under the weight of the structure, the mechanism becomes unbalanced and must be regularly tightened.
The process is based on independent work with a screwdriver (cross, straight) and a set of L-shaped keys. When skewed, the horizontal displacement is adjusted, when the threshold is clinging - vertical, when the pressure weakens - switch the "winter-summer" mode using the regulator on the end part. The procedure usually takes no longer than 30 minutes.
Selecting loops yourself is easy. You will need to take into account the conditions of use, the manufacturer of the accessories, and operating recommendations.
Accessories for plastic windows and doors
Metal-plastic doors cannot do without such an element as hinges. Door hinges are the most important component of the reliability and functioning of the door. All plastic doors are different. The reason is that today there are a huge number of different profile systems. We present hinges that are suitable for all existing profile systems.
Our hinges for plastic entrance doors include:
-Wide range of colors, compatible with the colors of other components
-High quality and attractive design
-Smooth adjustment in 3 planes with the participation of only one person, without the need to remove the leaf from the door frame
-Reliable and durable design
Types of hinges for plastic doors
According to this criterion, hinges are distinguished: collapsible; adjustable. The design of the former is no different from ordinary door hinges, and they are cheap. The design of the second type of loops is fundamentally different, which assumes the possibility of slight displacement. It is this that allows for adjustment, preventing distortions, rubbing, and squeaking.
Hinges for plastic doors are dismountable and adjustable
The lower and upper hinges also differ - the first one has a fixed axis, and therefore cannot be disassembled. Mostly, the upper one is adjustable, and the lower one is installed at the discretion of the master, depending on the design features and the weight of the door leaf.
Hinges for plastic doors are interchangeable, but they are conventionally divided into 2 types: for balcony doors; for input.
Their operating principle is similar, but spare parts for entrance doors are often equipped with a safety screw that prevents unauthorized removal of the hinge. The balcony door hinge is made taking into account the greater load due to the presence of a double-glazed window.
How much a loop costs depends mainly on the permissible load. Obviously, a cheap balcony hinge is useless. Price in this case serves as a guide to quality. In addition, the cost may vary depending on the color - non-white products cost a little more. But usually it’s a matter of a few hryvnias.

Hinges for fastening PVC doors
To attach the door leaf to the frame and ensure their opening, specialized hinges are used. It is on them that the door opens to the required width; they are used for hanging the canvas and ensuring safety. Let's look at what kind of loops there are and how to choose them correctly. There are many types of hinges with which you can hang a door leaf.
We list the most common options:
- overhead: placed on top of the frame and door, they are considered the most common. Allows you to adjust the correct installation of the door leaf in three planes, without the need to remove the door;
- screw-in hinges: they are two cylinders rotating relative to each other. They are attached to the door and door leaf using special dowels or self-tapping screws and have a decorative appearance. Well suited for lightweight interior doors;
- applied hinges: allow you to adjust the correct installation of the door leaf in three planes by installing additional spacers.
To attach the plastic door leaf to the frame and ensure their opening, specialized hinges are used
The most commonly used are classic overhead loops. They are usually made from brass or durable steel, but recently many inexpensive crafts made from aluminum and its alloys have appeared. Aluminum hinges quickly fail and break under light loads, so their use is not recommended.
To choose the right hinges for PVC doors, you need to understand which doors will be attached and how they should be opened.
Be sure to consider:
- door profile width. For wide profiles, hinges up to 110 mm wide are suitable, for narrow ones – up to 90 mm;
- door weight: doors weighing up to 80 kg are usually hung on narrow hinges, and up to 150 kg on wide hinges. There are special reinforced hinges that can withstand heavy loads, but in most cases a PVC door rarely reaches 60-80 kilograms of weight;
- profile overlay thickness (usually in the range from 15 to 20 mm);
- in which direction the door will open, what fastening systems will be used in your case;
- Is it necessary to adjust the door leaf after hanging? Classic hinges for PVC doors allow you to adjust the vertical and horizontal tilt of the leaf, as well as determine the force of pressing the door to the frame.
When choosing hinges for doors, be sure to pay attention to the manufacturer.
Installing a hinge for plastic doors
Door hinges are made mainly of metal alloys, and parts that are subject to significant loads are made of stainless steel and Teflon material of special strength. In order to understand how a door hinge is designed, you need to understand what elements it consists of.
The main elements of the loop are:
- door part and metal insert;
- frame part: it includes built-in pins for fastening;
- spacer sleeve, which is usually located between the frame and door parts. It is made of durable Teflon.
Hinges for a plastic door are no different from ordinary hinges, but the design of the hinge itself is different.
The main difference is that they are designed in such a way that they can be used to adjust the position of the door that is attached to them. Because of this feature, it is possible to move the doors a few millimeters in all directions in order to achieve an ideal fit of the leaf and the functionality of all locks.
Installation of the loop is carried out using a metal tab, which is fixed at the location of the future location of the loop. It is with its help that the door can be adjusted in all horizontal directions. As for adjusting the hinge in the vertical direction, it is done due to the fact that special adjustment screws are installed at the end of the hinges.
The thoughtful design of the hinges allows them to be used for a long time due to some technical solutions:
- High-strength Teflon is used in the design of the hinges;
- ball bearings are built into the hinge design;
- The hinge design is quite easy to lubricate if necessary.
Individualities
Throughout their entire operational life, door hinges are subject to enormous overloads. For this reason, they are created from strong materials such as alloy, stainless steel and Teflon.
The purpose of hinges for plastic balcony doors is to secure the system to the main frame, as well as to perform opening and closing. At the moment of closing, the canvases are tightly attached to the frame, due to which cool air does not penetrate into the room.
The door hinge is constructed from the following parts:
- tripod. It is used to fix the canvas;
- iron tabs (installed on the canvas);
- bushings. They are most often created from Teflon.
Visually, the hinge, which is used to construct plastic structures, is similar to the analogue that is installed on interior doors. But there is one obvious difference: the hinges for plastic gaps must be adjusted in an invariable manner after installation.
Using this function, you can easily adjust the entire process of opening and closing the door. This also avoids obvious gaps that may form between the doors and the frame.
In most situations, the hinges are installed using a special template, which makes it possible to adjust the system horizontally.
Vertical adjustment is carried out with a special screw
Vertical adjustment is done using a special screw, which is located on the hinge. These screws are hidden behind a strip, which will protect the system from dust penetration throughout its entire operation.
If necessary, the protective strip can be easily removed and then adjusted. To learn how to adjust the balcony door fittings, watch this video:
How to install hinges on plastic doors
To replace the hinges of plastic doors, the most common tools will be enough: a punch or a hammer; screwdrivers; pliers.
How to properly remove a plastic door from its hinge
Removing a plastic door differs from ordinary wooden doors due to the design of the hinges. The first step is to remove all the decorative caps from the hinges that cover them.

Next, you need to take a punch or hammer and very carefully knock out the axial mechanism. It is important that the door is closed, but not completely closed. After this, a small part of the axial mechanism will appear at the bottom of the loop, which must be grabbed with narrow pliers and pulled down until it completely jumps out of the loop.
Then the door needs to be slightly tilted towards you and held well, since it is quite heavy. The door leaf needs to be lifted up a few centimeters (about 5 cm), due to which the lower support pin will be released. Due to the fact that the lower hinges are not secured by anything, lifting the door and moving it to the side will easily remove it.
How to change hinges on plastic doors
Replacing the old hinge is quite easy. To do this, you need to remove the old, failed loop, and then replace it according to the instructions for the new loop.
To do this, you need to unscrew all the screws that secure the old hinge, remove the old hinge and screw a new one in its place.
If the door is under warranty, then it is best to seek help from the company that manufactured and installed the door. After replacing the hinges on the plastic door, the door can be returned to its place.
To do this you need:
- place the door and lift it a few centimeters, then put it on the support pins;
- After this, the lower hinge spring must be inserted into the support pin. The door should be closed, but not completely;
- the axial cylinder must be inserted from below into the hole in the upper hinge, while taking into account the edge on the cylinder;
- then the cylinder must be pushed from the bottom up so that it protrudes from the top and bottom by 5 mm;
- Finally, all the decorative plugs are put on the hinges. Installation is complete.
Tips for use
To make the hinges last longer, they need to be lubricated. To do this, you can use WD-40 or other similar greasy lubricants. Machine or refined oil or hot wax are very suitable. This function should be carried out from time to time, which will increase the reliability of the part. Lubricating the hinges involves the following steps:
- open the door very much;
- Place a small beam or several rolled newspapers below so that the system rises;
- pull the pin out of the loop or move it aside;
- draw the product into a small syringe and lower it into the hole where the pin was;
- place the pin on the space, remove the block from below;
- Close and open the door a couple of times so that the lubricant saturates the entire hinge.
Door hinges for metal-plastic structures
For long-term operation of aluminum and metal-plastic doors and windows, it is important to correctly select the appropriate fittings and especially hinges. The convenience, ease and safety of their operation directly depend on the level of quality of door and window hinges for structures made of PVC and other materials.
The main structural elements of such loops include:
- a body consisting of a frame (equipped with a pin) and a sash (with a metal insert) parts;
- connecting sleeve;
- special fasteners.
At the moment, modern hinges for metal-plastic doors can be adjusted vertically, horizontally and the degree of pressure. The fittings are designed for fabrics weighing from 80 to 130 kg or more.
Types of hinges for metal-plastic doors and their design
Hinges for plastic doors come in several types. Their choice is primarily related to the functional purpose of the structure in which they are used. In this regard, it is necessary to decide what function the door block will perform.
A balcony door differs from a plastic window only in its relatively large size, but it performs the same tasks of opening and ventilation, so the same components are used for the manufacture of such products as for the window. In this case, window hinges for doors are used, and the design of hinges on metal-plastic doors is no different from window fittings. Such hinges are made of a special alloy of aluminum, zinc and magnesium, which provides maximum protection against corrosion.
In addition, this gives the hinges additional strength and reliability, increasing their ability to withstand sufficient loads. Typically, the load capacity of hinges used in translucent balcony structures ranges from 80 to 130 kg.
It is worth noting that as the size of the sashes increases, their weight increases and the load on the hinge system increases. Moreover, the maximum weight of a sash with an area of 2.4 m? is 100 kg. These indicators must be taken into account when calculating the permissible dimensions of balcony door leaves. Also, you should not weigh down the door structures with double-glazed windows.
Unlike balcony blocks, metal-plastic entrance doors, being the main entrance to the room, are subject to additional load due to numerous daily openings of the doors, as well as having greater weight. As a result, reinforced hinges are used in the production of entrance doors. In addition, entrance doors usually open outward, therefore, located on the outside of the door, the hinges must meet the requirements of safety and durability in operation.
There are different types of hinges for metal-plastic doors, but most often so-called overhead hinges are used for entrance doors
There are different types of hinges for metal-plastic doors, but most often so-called overhead hinges are used for entrance doors. As in window fittings, these hinges act as an element connecting the door leaf to the frame frame and ensuring its normal opening and closing. Today, the window market is represented by a wide range of hinge groups of different shapes and designs, however, the design of plastic door hinges and the principle of their operation are similar, regardless of the manufacturer.
The door hinge kit includes a frame part with two fastening pins and a door part with a metal insert installed on it. These elements are connected using a durable Teflon or plastic sleeve with a removable steel pin. Each hinge is supplied with the mounting screws necessary for its installation, and is also accompanied by instructions for installing the door hinge.
The body of the frame and door parts are made of an alloy of aluminum, zinc and copper, which gives them special strength and increases the load capacity of the door hinge to 160 kg. Based on this, the number of hinges on the door can be limited to 3 pieces, two of which are installed at the top, and the third at the bottom of the door.
Hinges for swing doors have a completely different structure. Unlike overhead hinges, they are mounted to the end of the sash or in its upper and lower corners, while the door frame design does not have a rebate. Thanks to these features, swing doors can swing freely both inward and outward.
Adjusting plastic doors yourself: instructions
Before you start adjusting the entrance or balcony plastic doors, check the integrity of the seal. Often its defects become the cause of drafts and leaks. If the seal is damaged, replace it with a new one. In this case, there is no need to disassemble and adjust the mechanisms.
Before starting repair work, close the doorway and outline the frame around the perimeter. The contour should be parallel to the inner edges of the door frame. If there are curvatures, you need to eliminate the sagging of the sash and adjust the canvas in height.
First remove the decorative trims from the hinges, this will provide access to the screws.
Door pressure adjustment
Loosely fitting doors lead to drafts in the house and the formation of condensation on the glass. Before you start adjusting the door pressure, you need to determine the place where the gap appears.
If there are areas where the sashes do not fit tightly, you need to correct the defect by turning the axles. These are bushings at the end of the door frame, located along its perimeter. When the door opens and closes, they move.
On one side of the pins there is a mark or a stamped point - this is a mark. It should be directed upwards. To make the clamp tighter, turn the axle with the hexagon mesh towards the room. So the door is switched to “winter” mode. To loosen the fit, turn the mechanism towards the street.

The pressure of the sashes is also adjusted using the lower hinges. Open the door and look at the door leaf: you will see a screw at the bottom. Rotate it to obtain the required pressure on the door leaves.

If both methods of adjusting plastic doors did not help, the problem lies in deformation of the structure or incorrect installation. To eliminate the defect, move the strike plate 1–2 mm closer to the street and secure it.
Adjusting the plastic door height
Sagging of the sashes more often occurs with double-chamber double-glazed windows - they have more weight and more load. To lift the sash, you need to rotate the screw on the bottom hinge. To do this, take a 4 mm hexagon and turn it clockwise - the canvas will rise, counterclockwise - it will fall. This method helps if the canvas has sunk evenly around the entire perimeter.

The skew of the door leaf is indicated by the sagging of one side relative to the bottom edge of the opening. To level the defect, adjust the upper and lower side loops. Turn the screw with a hexagon. If you turn to the right, the canvas moves in the direction of the key, if you turn to the left, in the opposite direction.

Displacement of the blade leads to an increase in the load on the glass. If the defect is not corrected, the glass unit will burst.
If moving the adjusting screws does not help, the sagging is corrected with pads under the glass unit. To install them, the glazing beads are dismantled and calibrated wedges are installed. Leave repair work to the masters: you must strictly follow the technology so that the door does not become deformed.
Adjusting plastic door hinges
The hinges of the door panels are adjusted if their lower part catches the frame or does not fit tightly. The problem arises in the autumn-winter period, if the fittings are relegated to a corner. To eliminate the defect, the sash is moved horizontally: the position of the top and bottom hinges is adjusted.
Attention! To adjust the plastic profile, tighten the upper and lower hinges. If you adjust only one, then the position will change only at this point. The entire profile may become deformed.
The sequence of actions is as follows.
Open the door and trace the outline of the canvas with a simple pencil. If both edges are equidistant from the inside of the installation box, you can complete the adjustment of the plastic door.

The back adjusting screw may be located in the corner or above the door leaf.
Adjusting plastic door fittings: handle repair
The handle is attached to the door with two screws. Over time, the structure becomes loose, the fastening needs to be tightened. To do this, turn the plastic plug hiding the screws 90°. Screw the screws until they stop.
Two screws are hidden under the plastic plug.
If you cannot turn the plastic plug, pull the door handle towards you and try again. Loose screws may rest against the plug and interfere with rotation.
If the handle turns worse after repair, remove the plastic plug again and loosen the screws a little. Try opening and closing the door again.
If the handle closes poorly, does not turn completely or creaks, you need to correct the coupling of the pin with the strike plate. The principle of operation is the same as in the case of the clamp: turn the axle with the mark towards the street, that is, move it to the “summer” position.
Breakage of the handle may be the result of incorrect adjustment of the balcony door. In this case, the sequence of actions is as follows.
If the above adjustment methods did not help, this means that the problem lies in the wear of the belt mechanism.
Adjusting the fittings of a plastic door includes working with hinges. If during operation they become loose and begin to wobble, you need to tighten them with a hex wrench. If the lower fastening is torn out, you need to change the hinge. There are two reasons for the breakdown.
If the handle makes sharp sounds when opening and closing the front door, remove the handle and lubricate the mechanism. If lubrication of the moving parts does not help, you need to change the locking system.

Methods for caring for hinges for plastic doors
If for some reason you have removed the door from its hinges, do not rush to put it back. The hinges may need some care, so taking advantage of the moment to treat them will not be a bad idea.
To do this, you need to know how to lubricate the hinges of a plastic door correctly:
- Wash the removed structure to remove debris and dust that has accumulated in it. This can be done using gasoline;
- the surface must be wiped dry and any remaining dirt removed;
- after this, you can lubricate the structure with a special lubricant: it can be a solid substance for hinges or a liquid that is sold in specialized stores. The second option is the most convenient, as it is packaged in a convenient grease container, which makes it convenient to apply lubricant. This can be done even if the door is in place.
To lubricate the hinges and mechanisms of a plastic door, you must use only special oil; you should not use substances not intended for this purpose.
