Hager Hinge 050220 Spring Hinge 4x4 Bright Brass

Product Description

The HAGER HINGE 050220 is a full mortise, single-acting spring hinge designed for commercial and residential door installations requiring controlled, automatic door return. Built from steel with a bright brass finish, this 4 inches x 4 inches hinge features 1/4 inches radius corners and an arc hole pattern that aligns with standard mortise hinge preparations. It ships with both wood and machine screws included. A spring pin mechanism provides the tension needed to return the door to a closed position after each use, making it well suited for interior doors in commercial corridors, office suites, and institutional settings where self-closing function is required.

This hinge is intended for full mortise door applications where the hinge leaf is recessed into both the door edge and the frame. It is appropriate for single-acting swing doors in commercial environments. The bright brass finish suits interior applications where a traditional metal appearance is specified. The included hardware makes it ready to install without sourcing additional fasteners. Installation is typically handled by a finish carpenter, door hardware installer, or commercial door contractor.

Installation Notes

Installation is performed by a qualified door hardware installer or finish carpenter. The door should be fully removed from service and all spring tension released before disassembling or replacing an existing spring hinge. Follow ANSI and local building code requirements for door hardware installation, including self-closing requirements in rated corridor applications. Do not over-tension the spring mechanism beyond the designed range of adjustment.
