National Mfg N222-331 Square U-bolt Plate 3/8x3 Zinc 10pk

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N222-331 is a zinc-plated square U-bolt plate designed to secure U-bolts in pipe, conduit, and structural fastening applications. Measuring 3/8 inches by 3 inches, this plate distributes clamping load evenly across the mounting surface when used in conjunction with a standard U-bolt assembly. The zinc finish provides corrosion resistance suitable for general indoor and light-duty outdoor installations. Sold in a bulk pack of 10 units, the N222-331 is a practical stock item for plumbers, pipefitters, electricians, and general contractors who regularly install or service U-bolt assemblies.

This square U-bolt plate is used in residential and light commercial installations where pipes, conduit runs, or round structural members require secure clamping to a flat surface. The 3/8-inch fastener size and 3-inch plate width cover common pipe and conduit diameters found in typical mechanical and electrical systems. The bulk pack quantity makes it well suited for larger jobs or van-stock replenishment.
