National Mfg N351-506 Corner Brace 6 in Black Steel 5 Pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N351-506 is a black powder coated steel corner brace designed to reinforce 90-degree angles in building material assemblies. Each brace measures 6 inches in length with a plate thickness of 1/8 inch and a plate width of 3 inches. The powder coat finish provides corrosion resistance for interior and light exterior applications. Plate width and bolt hole placement are configured to offer multiple options for structural support positioning. This hardware is installed by carpenters, contractors, and general trade professionals working on framing, shelving, and structural reinforcement tasks.

This corner brace is suited for residential and light commercial construction and remodeling applications where right-angle joints require added rigidity. Common use cases include reinforcing shelf brackets, cabinet framing, furniture joints, and wood or metal structural connections at 90-degree intersections. Each package contains 5 braces sold as a boxed loose unit, making it practical for projects requiring multiple fastening points. The brace is applied to the side face of the angle joint rather than the outer corner surface.
