National Mfg N351-495 Corner Brace Black Steel 5 Pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N351-495 is a black powder coated steel corner brace designed to reinforce 90-degree angles in structural and finish carpentry applications. Measuring 2.4 inches by 3 inches with a material thickness of 3/16 inches, this brace applies to the inside or outside of a corner joint to add rigidity and load resistance. The square profile features multiple bolt slots per side, providing a wider bearing area for attachment to broader building materials. Chamfered corners give the finished installation a cleaner appearance. Sold in a pack of 5 units, this brace suits structural reinforcement tasks handled by carpenters, contractors, and experienced DIYers working with wood framing, cabinetry, or furniture assembly.

This corner brace is suited for residential and light commercial construction projects where 90-degree joint reinforcement is required. Typical applications include framing corners, shelf supports, workbench construction, cabinet assembly, and general woodworking. The black powder coat finish resists corrosion and blends with painted or dark-finished surfaces. Two material thicknesses are available across the product line to match varying load and application requirements. At 3/16 inches thick, this version handles moderate structural duty while remaining unobtrusive at the joint.

Installation Notes

Installation is typically performed by carpenters or general contractors using standard hand tools including a drill, appropriate fasteners, and a square to confirm the joint angle before securing. Power down any electrical circuits in the work area before drilling into walls or framing. Fasten through the bolt slots using appropriately sized screws or bolts for the substrate material. Do not over-torque fasteners into wood substrates, as this can compress or split the material at the slot edges.
