National Mfg N351-505 Corner Brace 6.5 in Black Steel 5-pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N351-505 is a black powder coated steel corner brace designed to reinforce 90-degree angles in structural and finish building applications. Each brace measures 6.5 inches in length with a 1.5-inch width and 1/8-inch thickness, providing solid support at framing joints, shelving connections, and similar right-angle assemblies. The powder coat finish offers corrosion resistance for both interior and exterior use. This SKU ships as a boxed loose pack of 5 individual braces, making it practical for jobs requiring multiple reinforcement points. Carpenters, finish contractors, and general tradespeople install these braces where additional mechanical support is needed at angle joints.

The N351-505 corner brace is suited for residential and light commercial construction and repair work. Typical applications include reinforcing cabinet frames, wood shelving brackets, door frames, furniture joints, and general structural connections where a 90-degree angle must be held under load. The brace is applied to the side face of the angle joint rather than the inside corner, allowing flat surface contact on both legs for a secure fastened connection. The pack-of-5 format supports multi-point installations on a single project without reordering.

Key Features

• 6.5-inch length with 1.5-inch leg width for substantial bearing surface at the joint
• 1/8-inch steel thickness provides rigid support at 90-degree connections
• Black powder coat finish for corrosion resistance and clean appearance
• Side-application design mounts flat to the face of the angle for full surface contact
• Pack of 5 braces per box for multi-point installations

Compatibility

Designed as a general-purpose OEM-style corner brace suitable for wood, metal, and composite building materials requiring 90-degree angle reinforcement in residential and light commercial construction applications.

Installation Notes

Corner braces of this type are installed by licensed carpenters or general contractors using standard fasteners appropriate to the base material, typically wood screws or self-tapping metal screws. Ensure the mating surfaces are clean, flush, and square before fastening to maintain the intended 90-degree geometry. Always pre-drill pilot holes in hardwood or composite materials to prevent splitting. Follow applicable local building codes when using corner braces in load-bearing or structural assemblies.
