National Mfg N139-659 2 Inch Steel Removable Pin Broad Hinge

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N139-659 is a 2-inch plain steel removable pin broad hinge designed for full mortise door installations. Manufactured from cold rolled steel, this five-knuckle hinge features a swaged profile that seats flush in mortise cutouts for a clean, finished fit. The loose pin design allows doors to be removed from the frame without detaching the hinge leaves from either the door or the jamb. It ships boxed loose and is sold in a package quantity of 10. This hinge is a standard hardware component installed by carpenters, millwork contractors, and general contractors during door hanging or replacement work.

This hinge is suited for residential and light commercial door applications where a full mortise, removable-pin hinge is required. The full mortise configuration means both leaves recess into the door edge and door frame, keeping the hinge body flush with the surface. The loose pin feature is especially practical in high-traffic or service environments where doors need to be removed and rehung without disturbing the installed hinge hardware. Typical applications include interior passage doors, closet doors, and utility room doors.

Installation Notes

Installation is performed by carpenters or general contractors using a chisel and mallet to cut mortise recesses in the door edge and door jamb. Power down any automated door hardware before servicing hinges on electrified door assemblies. Ensure mortise depth matches the hinge leaf thickness to achieve a flush surface. Follow local building codes for minimum hinge quantity and placement requirements on fire-rated or exterior doors.
