Fire Rated Concealed Leaf Full Mortise 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. Not only does this reduce hinge failure, it also 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. The geared continuous hinge has no pin. Instead, these hinges utilize a single gear section for the leaf and a separate gear section for the frame side of the door. The design of a continuous hinge eliminates the spacing between the hinges, which helps prevents fingers from being pinched, making it a safer device than traditional hinges.
