National N190736 Zinc Spring Door Hinge 2.75 in 2-pack

Product Description

The NATIONAL N190736 is a zinc spring door hinge sold in a 2-pack, designed to provide self-closing action on standard interior and light commercial doors. The spring mechanism integrated into the barrel applies consistent return tension so the door closes automatically after each use. At 2.75 inches, this hinge suits typical passage doors found in residential and light commercial settings. Installation requires only basic hand tools and no specialized trade license, making it a practical hardware solution for door hardware replacement or new installation work.

This spring hinge is suited for residential interior doors, utility rooms, and light commercial doorways where self-closing function is required. It is commonly specified on doors that need to meet basic self-closing requirements without a full overhead closer. The 2-pack provides enough hardware to replace a pair of standard hinges on a single door leaf.

Install with the door closed and power tools or hand tools suitable for wood or hollow-core door materials. Remove the existing hinge fully before mounting the spring hinge to ensure proper mortise fit. Adjust spring tension using the adjustment pin included or a compatible tool before final installation. Verify door alignment and swing clearance after installation to confirm proper self-closing function.
