Hinges and pintels for doors

Difference between hinge and lift-off hinge for doors

We call a lift-off hinge or hinge the axis upon which a door rotates. The main difference between the two lies in the fact that the lift-off hinge is separable and the hinge is not. This separability means that lift-off hinges are handed, and depending on whether the door opens to the right or left, you will need right-hand or left-hand opening lift-off hinges. In contrast, hinges are not separable and will work for doors opening on either side: right or left.

The hinge sector is large and complex. Depending on the material, door, intended use, legal requirements, method of installation, method of opening, and method of closing, you will need certain models over others, and the installation will also be specific. We are going to look at the types of hinges that exist in the sector so that you can learn to identify which one you need and how to install it.

The hinge for kitchen doors

Hinges for kitchen doors, that is, hinges for furniture and cabinets, are always special and specific. Depending on millimeter differences and opening angles, you will need one model or another. Typically, in kitchens, there are 3 types of hinges that are most commonly seen and installed:

1. Piston hinge

The piston hinge is a type of hinge that operates with gas. It is typical to see it installed on drop-down and lift-up kitchen doors, and its function is to assist in lifting the door or braking the descent so that it does not hit the cabinet. There are piston hinges with different opening and closing forces, and the model you need will depend on the weight of the door.

2. Concealed hinge (cup hinge)

Concealed hinges (cup hinges) are the most common type of hinge for kitchen doors. The best-sellers are known as full overlay, half overlay, and inset hinges, and taking into account the type of door and its closed position, you must choose the correct model.

3. Hinge for drop-down and lift-up doors

There are also doors that open vertically. These doors usually open with spring-loaded hinge arms that help to lift the door and keep it in the position you need.

The hinge for wooden doors

Wooden doors can have either a lift-off hinge or a hinge as their rotation axis. The lift-off hinge allows for easier installation as well as quick mounting and dismounting. Conversely, the hinge must be placed on both sides at the same time (unless it has a pin that dismounts the hinge). Furthermore, hinges can be installed on right-hand and left-hand opening doors interchangeably, whereas lift-off hinges can be either for right-hand or left-hand opening doors. In general, we recommend opting for lift-off hinges when dealing with simple interior doors made of wood. The lift-off hinge is well-priced and easy for anyone to install.

On the other hand, when we talk about hinges for wooden doors, we find numerous different types and models. These are some of the most typical:

1. Concealed hinges for doors

This type of invisible hinge is an option whenever dealing with delicate interior design projects where paying attention to detail, elegance, and harmony is paramount. It is important to clearly understand the function of this type of hinge, how it is installed, and the characteristics your doors must have to be able to fit a concealed hinge. Invisible hinges have sophisticated mechanisms such as an integrated braking system or the option to adjust the opening.

2. Butt hinges

Butt hinges are a type of hinge very commonly installed on wooden doors. These consist of two parts joined by a central axis whose function is simple: opening and closing the door.

3. Piano hinges

Piano hinges are elongated butt hinges that run along the entire edge of the door. They can be any length, although the standard measurement is one meter.

Other types of hinges for doors

Although the above hinges are the best-sellers, there are also other types of hinges, such as stainless steel hinges for exterior doors, hinges for heavy iron doors, hinges for armored doors, or hinges for pivoting doors.

The hinges for aluminum doors

Aluminum is a very widely used material, especially when it comes to doors that lead to the exterior. Typically, windows and exterior doors are fire-rated and usually carry a specific type of hardware and special hinges. Furthermore, unlike wood, which is a material that can be easily worked and adapted, aluminum has set measurements and dimensions, and therefore the hinge must be of exact measurements to fit the frame.

Hinges for heavy doors

Hinges for heavy doors are larger and longer than normal. These are superimposed onto the door and cover a large part of it. They are used for large, heavy gates and exterior doors. Their installation is carried out using lag screws and they are manufactured to withstand high intensity of use.

Hinges for glass doors or shower screens

Finally, within the world of hinges, there are hinges for glass doors. These are simply characterized by being a hinge with rubber or silicone protection that grips the glass by exerting pressure on it.
