National Mfg N351-454 3 Inch Black Steel Mending Brace 5 Pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N351-454 is a black powder coated steel mending brace designed to reinforce miter joint connections that form a 90-degree angle. Measuring 3 inches in length with a plate width of 1.3 inches and a thickness of 1/8 inch, this flat brace provides a low-profile reinforcement solution for interior framing, trim, and finish carpentry applications. The 45-degree angled hole pattern allows nails to be driven at an angle into the joined pieces, improving holding strength without requiring additional hardware. Each package contains 5 braces and ships boxed loose. The black powder coat finish resists corrosion and blends with painted or dark-finished surfaces.

This mending brace is suited for residential and light commercial finish carpentry, furniture repair, cabinet assembly, and millwork applications where two miter-cut pieces meet at a 90-degree corner. Carpenters and trim installers use this brace to add mechanical reinforcement to glued or nailed miter joints that are subject to stress or seasonal wood movement. The compact profile keeps the brace unobtrusive once the joint is finished or painted over.

Installation Notes

Installation is performed by carpenters or trim professionals using standard finish nails or screws through the angled hole pattern.

No power tools are required for basic nail installation, though a drill may be used if driving screws. Always follow applicable local building codes for structural or load-bearing applications.
