National Hardware N276-980 Stainless Steel Door Hinge, 3 X 3 In., Full Mortise

This National Hardware stainless steel door hinge is a heavy-duty hardware solution for interior and exterior doors in residential, commercial, and industrial settings. The 3-inch by 3-inch square corner design with full mortise mounting ensures a professional, seamless finish that sits flush with the door and frame, with no protruding hardware. Stainless steel construction provides maximum corrosion resistance, making it ideal for marine environments, coastal applications, and other outdoor conditions where standard hinges would rust or degrade.

The hinge features a non-rising pin that stays firmly in place. Its removable pin design simplifies installation and maintenance. With a 50-pound weight capacity, this hinge supports standard residential and light commercial doors. The NIB finish on the hinge's lower edge creates a clean, finished appearance, and countersunk screw holes ensure a flush, snag-free surface.
