National Mfg N115-006 Adjustable Spring Hinge 3in Brass 2pk

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N115-006 is a full surface adjustable spring hinge designed to automatically return doors to a closed position after use. Sold in a 2-pack, each hinge measures 3 inches and features a baked enamel brass finish for durability and corrosion resistance. Mounting hardware is included. This type of spring hinge is a common solution in light commercial and residential applications where self-closing door function is required by code or preferred for convenience. Installation requires no mortising, as the full surface design mounts directly to the face of the door and frame.

This hinge is suited for interior doors in residential and light commercial settings where a self-closing mechanism is needed. Typical install scenarios include utility rooms, storage areas, and fire-rated door assemblies where self-closing hardware may be required under local building codes. The adjustable spring tension allows the installer to dial in the closing force appropriate for the door weight and application. Each pack includes screws for a complete installation.

Installation Notes

Installation is typically performed by a carpenter, general contractor, or qualified handyman. No mortising is required for full surface hinges, but door and frame surfaces should be clean and flat before mounting. Verify local building codes for self-closing door requirements, particularly in fire-rated assemblies. Adjust spring tension using the adjustment pin before final hardware installation to confirm proper closing force.
