National Mfg N351-500 Corner Brace 4.9 in Black Steel 5 Pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N351-500 is a black powder coated steel corner brace designed to reinforce 90-degree angle joints from the inside. Measuring 4.9 inches in overall length with a 3-inch leg width and 1/8-inch material thickness, this brace features an extended leg on one side to provide greater reach and improved structural stability. Chamfered corners give the hardware a clean, finished appearance. It is suitable for carpentry, furniture repair, cabinet installation, and general structural reinforcement tasks performed by contractors and skilled tradespeople.

This corner brace is used in residential and light commercial applications where inside-corner joint reinforcement is required. The extended leg design makes it well suited for situations where standard equal-leg braces do not provide sufficient bearing surface on one side of the joint. The black powder coat finish resists corrosion and blends with dark-finished woodwork and metal framing. This package contains 5 individual braces, sold as a boxed loose unit of measure.
