Hager Hinge 125041226D Spring Hinge 4.5x4.5 Satin Chrome

Product Description

The HAGER HINGE 125041226D is a full mortise, single acting square corner spring hinge finished in satin chrome. It measures 4.5 inches by 4.5 inches and is designed to provide controlled, self-closing door operation in commercial and light commercial door assemblies. The spring mechanism applies consistent return force to keep doors closed without a separate door closer, making it a practical choice for interior doors where code-required self-closing hardware is needed. At 1.25 pounds, the hinge offers solid construction suited to standard mortise door prep. Installation is typically handled by carpenters, door hardware specialists, or commercial contractors.

This spring hinge is intended for full mortise door applications where a square corner leaf profile is required. It is well suited to interior passage doors, corridor doors, and similar single-door assemblies in light commercial, institutional, or residential settings. The satin chrome finish blends with contemporary hardware trim packages. The single acting design allows the door to swing in one direction only, returning to the closed position after each use.

Installation Notes

Installation is performed by qualified carpenters or door hardware technicians familiar with mortise hinge prep. The door should be removed or properly supported before hinge replacement, and the spring tension should be set with the appropriate spring hinge tension tool before the pin is locked. Follow applicable building and fire code requirements when installing self-closing hardware on rated door assemblies. Do not exceed the door weight rating for the hinge count specified by the door manufacturer.
