National Hardware N220-111 Mending Plate 3.5 Inch Steel

Product Description

The NATIONAL HARDWARE N220-111 is a flat mending plate used to reinforce, attach, and splice wood panels, frames, and structural members in both residential and light industrial settings. Manufactured from hot-rolled steel with a zinc-plated finish, the N220-111 measures 3.5 inches in length and provides a rigid, corrosion-resistant connection point wherever added strength is needed. The zinc plating resists rust and surface oxidation, making it suitable for interior and protected exterior applications. Carpenters, general contractors, and skilled tradespeople install this type of mending plate as part of standard joinery, framing repair, and panel assembly work.

This mending plate is suited for reinforcing butt joints, splicing broken or split wood members, and attaching panels side by side in furniture, cabinetry, door frames, wall panels, and general construction assemblies. Its flat profile allows flush installation against any flat wood or composite surface without creating protrusions that would interfere with adjacent materials. The compact 3.5-inch size is well matched to light-duty structural repairs and medium-weight panel connections in both home improvement and light commercial maintenance contexts.

Installation Notes

Installation is typically performed by carpenters, general contractors, or maintenance tradespeople using standard fasteners appropriate to the base material. Power down any adjacent electrical systems before working in enclosed panels or wall assemblies. Pre-drill pilot holes in hardwood substrates to prevent splitting. Ensure mating surfaces are clean, flat, and fully seated before fastening to achieve rated joint strength.
