National Mfg N276-956 Ss Door Hinge 1-1/2in Square Corner 3-pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N276-956 is a 1-1/2 inch stainless steel full mortise door hinge designed for applications where corrosion resistance is a priority. Built from heavy-gauge stainless steel, this hinge features a 5-knuckle construction with square corners and a non-rising pin for consistent, long-term operation. The removable pin simplifies installation, and countersunk screw holes allow fasteners to sit flush for a clean finished appearance. A nib on the hinge body provides additional positional reference during mounting. Each package contains 3 hinges sold as a unit of measure of each.

This hinge is suited for residential and light commercial door installations where moisture exposure, humidity, or harsh environmental conditions demand a corrosion-resistant hardware solution. Full mortise design requires the hinge leaf to be recessed into the door edge and frame, which is standard practice for finish carpentry and door hanging work. It is appropriate for interior and exterior doors where stainless steel hardware is specified.

Installation Notes

Installation should be performed by a qualified carpenter or door hardware installer using a chisel and appropriate mortising tools to prepare the door edge and frame recess. Ensure the door is properly supported and secured before removing existing hardware. Countersunk screw holes accept standard flat-head wood screws; use fasteners appropriate for the door and frame material. Follow applicable local building codes for door hardware specifications on fire-rated or exterior assemblies.
