National Mfg N351-486 Corner Brace Black Steel 5 Pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N351-486 is a black powder coated steel corner brace designed to reinforce 90-degree angles in structural and finish carpentry applications. Each brace measures 7.125 inches in length, 1.6 inches in width, and 0.125 inches in thickness. The wider width compared to standard narrow braces provides a greater bearing area, making these braces well suited for long intersections of building materials where additional lateral stability is required. This item ships boxed loose in a pack of 5.

Corner braces of this profile are used in residential and light commercial construction, millwork, furniture repair, and general framing tasks. The inside or outside mounting geometry allows installers to apply the brace to either face of a corner joint depending on structural clearance and load requirements. Carpenters, general contractors, and maintenance technicians commonly use these in door and window framing, cabinet assembly, shelving reinforcement, and similar 90-degree joint applications.

• 7.125-inch length with 1.6-inch width delivers a broad contact surface for greater joint stability
• 0.125-inch material thickness provides rigid support at 90-degree angle intersections
• Designed for application to the inside or outside of a corner for versatile mounting options
• Wider width is particularly effective for reinforcing long intersections of building materials

Compatibility

Designed as a standard 90-degree corner brace suitable for use with common lumber, panel materials, and dimensional framing stock in residential and light commercial construction applications.

Installation Notes

Installation is performed with standard hand tools including a drill, screwdriver, and appropriate fasteners for the base material. Power down any electrical circuits in the work area before drilling into walls or structural members. Fasten through the pre-punched hole pattern and ensure the mating surfaces are flush and square before final tightening. Follow applicable local building codes when using metal connectors in structural assemblies.
