National Mfg N351-478 Corner Brace 7.5 in Black Steel

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N351-478 is a black powder coated steel corner brace designed to reinforce 90-degree angle joints from the inside. Measuring 7.5 inches in overall length with leg dimensions of 1.6 inches by 1.5 inches and a material thickness of 1/8 inch, this brace provides structural support at interior corner connections. One leg is extended longer than the other, giving additional reach to distribute load and improve joint stability. It is suited for carpentry, furniture assembly, cabinetry, and general construction repair work performed by contractors and skilled tradespeople.

This corner brace is used wherever an inside 90-degree joint requires added reinforcement. Typical applications include cabinet framing, shelving units, workbenches, door frames, and wood or metal assemblies that experience lateral stress. The inside-mount orientation keeps the brace concealed within the joint. The asymmetric leg design — with one leg providing extra reach — makes it especially effective where one surface has limited fastener area. Each package contains 5 braces, sold as a boxed loose unit.

Installation Notes

Installation is typically performed by carpenters, finish contractors, or skilled tradespeople using standard fasteners appropriate for the substrate material. Position the brace flush against both interior surfaces of the joint before fastening. Ensure the mounting surface is clean and flat to achieve full contact across both legs. Follow applicable building codes for structural applications where load-bearing connections are involved.
