National Mfg N830-430 3 Inch Full Mortise Hinge Black 15 Pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N830-430 is a full mortise door hinge finished in black, designed for residential and light commercial door installations. Built from heavy-gauge cold-rolled steel, this hinge offers solid structural performance in high-cycle applications. The five-knuckle design provides smooth, stable pivot action, while the flush pin delivers a clean, finished appearance once installed. Corners are finished to a 1/4 inch radius for a classic, rounded profile. Countersunk screw holes accept the included fasteners for a flush, professional fit. The removable pin simplifies door hanging and removal without special tooling.

This hinge suits standard interior and exterior door installations where a full mortise mount is required. The 3 inch leaf size is appropriate for interior passage doors, closet doors, and cabinet applications in residential construction and light commercial settings. Each package contains 15 hinges, making it suitable for multi-door projects or stocking purposes. The black finish coordinates with dark hardware finishes common in contemporary and industrial design applications. Licensed contractors, finish carpenters, and general tradespeople are the typical installers.

Installation Notes

Full mortise hinges are installed by carpenters and finish tradespeople using a chisel or router to cut a mortise recess into the door edge and jamb. Ensure the door and frame are properly squared before marking and cutting mortise pockets. Use the included fasteners and a hand screwdriver or low-torque driver to avoid stripping the countersunk holes. No power should need to be shut off for this hardware installation, but follow any applicable local building codes for door hardware in fire-rated assemblies.
