National Mfg N351-487 Corner Brace 1.6x9 in Black 5 Pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N351-487 is a black powder-coated corner brace designed to reinforce 90-degree angle joints in structural and framing applications. Measuring 1.6 inches wide by 9 inches long by 0.125 inches thick, this brace provides a wider-than-standard bearing surface that increases stability across long intersections of building materials. It can be applied to either the inside or outside of a corner. Mounting holes measure 0.375 inches in diameter. The black powder coat finish improves weather resistance, making this brace suitable for both interior and exterior installations. Each package contains 5 braces.

This corner brace is used by carpenters, general contractors, and skilled tradespeople wherever 90-degree structural connections need reinforcement. Common applications include framing lumber joints, shelving assemblies, furniture construction, and general building repairs. The extended 9-inch length and wider profile are particularly well suited for long intersections where a standard short brace would not provide adequate bearing area. It is appropriate for residential and light commercial construction tasks.

Installation Notes

Installation is typically performed by carpenters, framers, or general contractors using standard drill bits sized for 0.375-inch holes and appropriate wood or structural fasteners. Apply the brace flush to the corner surface before fastening to ensure full contact across the bearing area. Follow applicable local building codes for fastener type, count, and spacing when used in load-bearing applications.
