National Mfg N220-145 Zinc Corner Iron 4x7/8 in 10-pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N220-145 is a zinc corner iron used to reinforce and join structural corners in woodworking, furniture assembly, and general construction applications. Measuring 4 inches by 7/8 inches, this flat corner brace provides a low-profile metal reinforcement at right-angle joints. The zinc construction resists corrosion and offers adequate strength for interior framing, cabinetry, shelving, and repair work. Each package contains 10 corner irons, making it a practical choice for jobs requiring multiple installations. Carpenters, finish tradespeople, and maintenance technicians commonly use this type of hardware to secure mitered or butt-joined corners without adding significant bulk to the assembly.

This corner iron is suited for residential and light commercial applications including cabinet installation, furniture repair, door and window frame reinforcement, and general millwork. The compact 4-inch by 7/8-inch profile fits into tight corner spaces where larger brackets would be impractical. The package quantity of 10 units per pack supports both single repairs and multi-point installations in the same project.

Ensure the mating surfaces are square and clean before fastening to maintain joint alignment. No power disconnection is required for this hardware type, but always follow applicable building codes for structural applications.
