Constructed from heavy-gauge cold-rolled steel, this full mortise hinge delivers reliable load-bearing performance in residential and light commercial settings. The five-knuckle design provides stable pivot action, while the flush pin gives the installed hinge a refined appearance. Countersunk screw holes and included fasteners make mounting straightforward. This package contains 15 hinges, making it suitable for multi-door projects or contractor stocking.\u003c\/p\u003e\n\u003cp\u003eThe N830-424 is suited for interior door installations, cabinet doors, and millwork applications where a square-corner, full mortise hinge is specified.
