Best 711127850 Extra Heavy Full Surface Hinge 3in Steel

Product Description

The BEST 711127850 is an extra heavy full surface hinge designed for demanding door applications where both door and frame leaf mount on the surface rather than being mortised in. Constructed from steel with a plain finish, this hinge measures 3 inches in overall height and 3 inches in overall width, with a door leaf width of 1.5 inches and a frame leaf width of 1.5 inches. The non-removable pin adds tamper resistance, making it well suited for high-traffic or security-conscious installations. It weighs 0.45 pounds. Licensed contractors and millwork installers working on commercial or institutional door hardware projects are the primary installers.

Full surface hinges are used where mortising into the door edge or frame is not practical or desired, such as when retrofitting hollow metal doors, installing doors on masonry frames, or working with thick door assemblies. The extra heavy duty designation indicates a hinge built for doors subject to frequent use or above-average load. This hinge fits a nominal 3 x 3 inch size application and is sold individually.

Installation Notes

Installation is typically performed by a licensed door hardware technician or commercial carpenter. Ensure the door is properly supported and secured before removing any existing hardware. Fastener selection should be appropriate for the door and frame material to achieve full holding strength. Follow applicable building codes and door hardware standards for hinge quantity and placement based on door height and weight.
