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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStainless steel construction for maximum corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eFull mortise design with square corners for standard door prep\u003c\/li\u003e\n  \u003cli\u003e5-knuckle configuration for smooth, stable door operation\u003c\/li\u003e\n  \u003cli\u003eNon-rising pin maintains consistent hinge profile\u003c\/li\u003e\n  \u003cli\u003eCountersunk screw holes for flush fastener installation\u003c\/li\u003e\n  \u003cli\u003eRemovable pin for easier door hanging and alignment\u003c\/li\u003e\n  \u003cli\u003eNib detail provides finished appearance at hinge edges\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation hinge for standard full mortise door applications requiring a 2-1\/2 inch square corner stainless steel hinge.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by carpenters, general contractors, or skilled DIYers using a chisel, mallet, and drill with appropriate screwdriver bits.
