National Mfg N830-432 4 in Full Mortise Hinge Black 15 Pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N830-432 is a full mortise door hinge built for general construction and finish carpentry applications. Manufactured from heavy-gauge cold-rolled steel, this hinge delivers reliable strength in high-traffic door installations. The 4-inch leaf with a 1/4-inch radius corner profile gives it a clean, traditional look suited to residential and light commercial door hanging. The flush pin design keeps the finished appearance unobtrusive, and countersunk screw holes accept the included fasteners for a flush, professional install. This package contains 15 individual hinges, making it appropriate for multi-door projects or contractor restocking.

This hinge is used in standard door frame and door slab installations where a full mortise, five-knuckle hinge is specified. The 1/4-inch radius round corner profile fits mortised recesses cut to match that corner style. It is suited to interior and exterior residential doors as well as light commercial applications. Carpenters, general contractors, and finish tradespeople are the primary installers. The black finish coordinates with black door hardware sets on painted or dark-finished doors.

Key Features

• Heavy-gauge cold-rolled steel construction for added load strength

Compatibility

Designed as an OEM-style replacement or new-installation hinge for standard full mortise door applications requiring a 4-inch, 1/4-inch radius corner hinge in a black finish.

Installation Notes

Installation is performed by carpenters or general contractors using standard mortise chisels and a drill or screwdriver. Mortise the door slab and frame jamb to the exact leaf dimensions before mounting to ensure flush seating. Use all provided fasteners and verify that screw holes are fully countersunk to prevent leaf misalignment. The removable pin allows the door to be hung and removed without disturbing the mounted leaves.
