National Mfg N351-480 Corner Brace 7.5 in Black Steel 5 Pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N351-480 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 a profile of 1.6 inches by 1.5 inches and a material thickness of 3/16 inches, this brace is built for structural integrity in demanding applications. One leg is extended longer than the other to provide extra reach and improved stability at the joint. Sold in a pack of five loose-boxed units, it suits carpenters, general contractors, and skilled tradespeople working on framing, cabinetry, shelving, and structural reinforcement tasks.

This corner brace is suited for interior reinforcement applications where a 90-degree joint requires added support. The inside-mount orientation keeps the brace hidden within the assembly, making it practical for furniture construction, cabinet framing, workbench builds, and similar millwork or structural projects. The extended leg design addresses situations where standard equal-leg braces lack sufficient bearing surface on one side of the joint. Each pack contains five braces, making it practical for multi-joint installations in a single work session.

Key Features

• Inside-mount design reinforces 90-degree angle joints without exposed hardware on the exterior face
• Extended leg on one side delivers greater reach and improved joint stability
• Black powder coat finish provides corrosion resistance and a clean appearance
• 3/16-inch steel thickness offers solid load-bearing capacity for structural and millwork applications
• Sold as a pack of five for multi-joint installations

Compatibility

Designed as a general-purpose inside corner brace for 90-degree joint reinforcement in residential and light commercial woodworking, framing, and structural assembly applications.

Installation Notes

Installation is typically performed by carpenters, general contractors, or experienced DIYers using standard hand tools and a power drill. Power down or disconnect any adjacent electrical components before working in enclosed assemblies. Fasten through the pre-drilled mounting holes using appropriately sized fasteners for the substrate material. Follow applicable local building codes when using corner braces in structural load-bearing applications.
