National Mfg N351-464 Corner Brace 5.1 in Black Steel 5-pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N351-464 is a black powder coated steel corner brace designed to reinforce 90-degree angles in structural and finish carpentry applications. Measuring 5.1 inches in overall size with a 1.5-inch leg width and 1/8-inch thickness, this brace provides rigid support at inside or outside corners. The black powder coat finish offers corrosion resistance and a clean appearance on exposed installations. Each package contains 5 braces, sold boxed loose. This hardware is a standard fastening component installed by carpenters, general contractors, and skilled tradespeople working on framing, cabinetry, shelving, and furniture repair.

The N351-464 corner brace is suited for residential and light commercial applications where 90-degree joints require added mechanical reinforcement. It can be applied to the inside or outside of a corner, making it versatile for both structural framing reinforcement and finish work on wood furniture, shelving units, door frames, and similar assemblies. The black powder coat finish allows it to blend into painted or dark-finished surfaces without requiring additional coating after installation.
