National Mfg N220-178 Corner Iron 8x1-1/4 Inch Zinc 5-pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N220-178 is a zinc corner iron designed to reinforce and brace 90-degree joints in wood framing, cabinetry, shelving, and structural assemblies. Each piece measures 8 inches in length by 1-1/4 inches in width, providing a flat, pre-drilled metal brace that spans inside or outside corners to add rigidity and prevent racking. The zinc construction resists corrosion in typical interior environments. This hardware is commonly installed by carpenters, millwrights, and general contractors during rough framing, furniture fabrication, or repair work where corner strength is required.

Corner irons of this type are suited for residential and light commercial applications including wall framing connections, shelf bracket reinforcement, cabinet carcass assembly, and furniture repair. The flat-plate profile keeps the hardware low-profile against mating surfaces. This listing includes a package of 5 corner irons, making it practical for multi-joint projects or service vehicle stock. Fasteners are not included and should be selected based on the substrate material and load requirements of the specific application.

Key Features

• 8 inches x 1-1/4 inches flat corner iron profile for right-angle joint reinforcement
• Zinc construction provides corrosion resistance in interior service conditions
• Package quantity of 5 pieces per unit for multi-joint or stock applications
• Low-profile flat-plate design seats flush against wood or composite surfaces

Compatibility

Designed as a general-purpose corner brace for standard wood framing, cabinetry, shelving, and furniture assemblies where an 8-inch flat corner iron is the specified hardware.

Installation Notes

Corner irons are installed by carpenters or general maintenance trades using standard drill and screwdriver tooling. Position the iron flush across both faces of the corner joint before fastening to ensure proper alignment and load transfer. Select fastener length and gauge appropriate to the substrate thickness and the expected load. Follow applicable building codes for structural framing connections where load-bearing assemblies are involved.
