Hager Hinge 125041226D.1 Spring Hinge 4.5x4.5 Satin Chrome

Product Description

The HAGER HINGE 125041226D.1 is a full mortise, single acting, square corner spring hinge designed for commercial and residential door installations. It measures 4.5 inches by 4.5 inches and ships in a satin chrome finish. The spring mechanism allows a door to return to the closed position automatically after each use, making it a common choice in corridors, stairwells, and code-required self-closing door assemblies. This hinge is sold as a single unit and is installed by carpenters, door hardware specialists, or licensed contractors working on mortise-style door frames.

This hinge is suited for full mortise door applications where a square corner profile is required. It fits residential and light commercial door frames where self-closing function is needed to meet fire or egress code requirements. The satin chrome finish coordinates with standard commercial hardware finishes. At 0.9 pounds, the unit is lightweight and straightforward to handle during installation. The package dimensions measure 6.4 inches in length, 2.9 inches in width, and 1 inch in height.

Compatibility

Designed as an OEM-style replacement or new-installation spring hinge for full mortise, square corner door frames requiring a 4.5 inch by 4.5 inch single acting hinge.

Installation Notes

Installation is typically performed by a carpenter or licensed door hardware installer. The door and frame must be properly mortised to accept the square corner leaf profile before the hinge is seated and fastened. Confirm that the door assembly meets applicable fire or egress code requirements when a self-closing hinge is used in a rated application. Do not force or over-tension the spring mechanism during adjustment.
