Product Description

Continuous Geared Hinges are an innovative solution designed to extend the life of any entrance by distributing door weight across the entire frame. This unique design eliminates the concentrated stress typical of traditional butt hinges, effectively preventing door sag and ensuring perfect alignment over years of high-traffic use.

Featuring a pin-less design with two separate gear sections held together by a full-length cover, these hinges rotate smoothly on high-performance bearings. Safety is a primary benefit: the continuous design closes the gap between the door and frame, preventing fingers from being pinched, making it ideal for schools, hospitals, and public buildings.
