Hager Hinge 050274 Spring Hinge 4x4 in Satin Nickel

Product Description

The HAGER HINGE 050274 is a full mortise, single acting spring hinge designed for commercial door applications. Built from steel with a satin nickel finish, it measures 4 inches x 4 inches and features 1/4 inches radius corners for a clean, recessed fit in standard mortised door and frame preps. The spring mechanism automatically returns the door to a closed position after each use, making it well suited for corridors, utility rooms, and commercial spaces that require hands-free door closure. Installation is straightforward for carpenters, door hardware specialists, and commercial finish contractors working on wood or hollow metal door assemblies.

This hinge is intended for commercial door applications where a self-closing function is required without a separate overhead closer. The single acting design allows the door to swing in one direction only. The arc hole pattern and included wood and machine screws allow for direct mounting into standard mortise preps. It is appropriate for interior commercial doors in light- to medium-duty service conditions where code or facility requirements call for self-closing hardware.

Compatibility

Installation Notes

Installation should be performed by a qualified door hardware technician or finish carpenter familiar with commercial mortise hinge applications. Ensure the door and frame mortises are properly sized and squared before mounting. Adjust spring tension only with the door secure and appropriate spring adjustment tools - never release a loaded spring pin without proper control. Follow applicable local building codes and fire rating requirements when installing self-closing hardware on rated door assemblies.
