Fire Rated Continuous Geared Door Hinge
The Continuous Geared Hinges are designed to last the life of a building by distributing the weight of a door along the entire length of its frame. The unique design reduces the high amount of stress normally associated at the top of the door and frame on butt hinge applications. It keeps a door in constant alignment, eliminating the chance of door sag. These characteristics make continuous hinges suitable for high-use and high-traffic doors.

Frequently Asked Questions
What are the main benefits of using a geared continuous hinge?
Geared continuous hinges distribute the door's weight evenly along the frame, reducing stress on the top of the door and preventing sagging, which is common with traditional butt hinges.
