National Mfg N351-488 Corner Brace 2.1x5 in Black 5-pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N351-488 is a black powder-coated steel corner brace designed to reinforce 90-degree angle joints in structural and building material applications. Measuring 2.1 inches wide by 5 inches long by 0.125 inches thick, this brace can be installed on either the inside or outside of a corner. The wider width delivers a greater surface area of contact, improving stability across long intersections of framing lumber or other building materials. Larger bolt holes accommodate a 0.5-inch carriage bolt for flexible structural fastening. The black powder coat finish provides improved resistance to moisture and weather exposure. Each package contains 5 braces.

This corner brace is suited for residential and light commercial construction, carpentry, and renovation work. Typical applications include reinforcing wood framing joints, furniture assembly, shelving structures, and similar right-angle connections where added mechanical support is required. The slotted bolt holes allow for minor positional adjustment during installation, making it adaptable to varied build situations.
