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.
Key Features
- Reinforces 90-degree angles when applied to the inside or outside of a corner
- 1.6-inch width provides greater stability across long intersections of building materials
- 0.375-inch diameter mounting holes for standard fastener sizing
- Black powder coat finish for improved weather and corrosion resistance
- 0.125-inch material thickness for rigid support

Compatibility
Designed as an OEM-style structural corner brace suitable for use with standard dimensional lumber and common building materials requiring 90-degree angle reinforcement.
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.
