A Unique Friction Piano Hinge

This continuous friction hinge is sleek, simple and elegantly made to hold the position of cabinet doors, commercial displays, and even industrial equipment, preventing them from swinging further open or closed on their own. This makes their operation easy, convenient, and safe whether installed vertically or horizontally.

At 300mm, or 2¾ inches long, these friction piano hinges can be used on their own or in multiples for doors larger than 12 inches. Their tight build allows for reduced gaps between housing and doors for industrial equipment and shop fittings.

As a greaseless continuous friction hinge, it can be used in environments with exposure to water. It has successfully passed 30,000 private cycle tests, making it an incredibly durable stainless steel hinge for industrial, commercial, or high-end residential applications.
