Friction stay hinges, also known as tension hinges, are ingenious devices that provide friction to prevent doors and lids from swinging freely. They are commonly found in applications where controlled opening and closing are desired, such as kitchen cabinets, bathroom vanities, and office furniture.

Understanding Friction

Friction is the force that opposes the relative motion of two surfaces in contact. When a door is opened or closed, the hinges create friction between the two surfaces. This friction prevents the door from moving too quickly or slamming shut.

Components of a Friction Stay Hinge

Friction stay hinges typically consist of two main components:

Spring arm: A spring-loaded arm that provides the friction.

Friction plate: A plate that contacts the door or lid, creating the friction.

How They Work

When a door or lid is opened, the spring arm extends and presses against the friction plate. This creates friction, which resists the movement of the door or lid. The amount of friction can be adjusted by tightening or loosening the spring.

The tension in the spring determines the amount of resistance provided. A tighter spring will create more friction, making it harder to open or close the door or lid. Conversely, a looser spring will create less friction, allowing for smoother opening and closing.

Benefits of Friction Stay Hinges

Controlled movement: They prevent doors and lids from swinging freely, providing controlled opening and closing.

Safety: They reduce the risk of injuries from slamming doors or lids.

Convenience: They allow for easy opening and closing of doors and lids, especially in tight spaces.

Durability: They are built to withstand repeated use and maintain their friction over time.


Friction stay hinges are used in a wide range of applications, including:

Kitchen cabinets

Bathroom vanities

Office furniture

Storage boxes

Aerospace equipment

Their versatility and effectiveness make them an essential component for any design that requires controlled movement of doors or lids.
