National Hardware N351-493 Corner Brace, Black Steel, 3 X 6.6 In.

This National Hardware corner brace is a heavy-duty reinforcement bracket designed to strengthen 90-degree angles by mounting to the inside or outside of a corner. Cut from rolled structural steel, it delivers superior reinforcement strength compared to bent steel alternatives, making it ideal for securing furniture joints, door frames, wall corners, and other structural intersections where durability and stability matter.

The brace's wider 6.6-inch length provides a generous surface area for distributing loads across long material intersections, while larger bolt holes with 1/2-inch carriage bolt slots offer flexibility in fastening and structural support options. The black powder-coat finish provides weather resistance.

Features and Benefits

• Rolled Structural Steel Construction: Cut from rolled steel rather than bent, providing greater reinforcement strength and load-bearing capacity.
• 6.6-Inch Length with 3-Inch Width: The extended surface area distributes weight evenly across corner joints for maximum stability on long material intersections.
