National Mfg N276-972 Ss Door Hinge 2-1/2in Square Corner 3-pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N276-972 is a 2-1/2 inch stainless steel door hinge built for full mortise installation with square corners. Constructed from heavy-gauge stainless steel, it delivers maximum corrosion resistance in demanding environments. The 5-knuckle design provides smooth, stable door movement, while the non-rising pin keeps the hinge profile consistent during operation. A nib on the hinge body creates a clean, finished appearance once installed. Screw holes are countersunk for flush fastener seating, and the removable pin simplifies installation and alignment. Sold in a pack of 3, this hinge suits residential and light commercial door applications where moisture exposure or aesthetics require stainless hardware.

The N276-972 is suited for interior and exterior door installations where corrosion resistance is a priority, such as bathrooms, kitchens, coastal environments, or commercial entry points. The full mortise design requires a routed mortise pocket in both the door edge and the door frame. Square corner geometry matches standard mortise cutouts common in residential and light commercial door prep. Each pack contains 3 hinges, covering a standard single-door application.

Installation Notes

Installation is performed by carpenters, general contractors, or skilled DIYers using a chisel, mallet, and drill with appropriate screwdriver bits. Power down any electric door hardware before servicing hinges on automated or access-controlled doors. The full mortise design requires precise mortise routing in both the door edge and jamb to ensure flush seating and proper door swing. Use all provided screw holes to ensure load is distributed evenly across the hinge leaf.
