Product Description

The NATIONAL MARKER N222331 is a zinc-finished U bolt plate designed for use with 3/8-inch square U bolts. Manufactured from hot-rolled steel, this plate features a WeatherGuard zinc finish that provides superior corrosion resistance in exposed or demanding environments. Measuring 3 inches in length and sized for 3/8-inch U bolt hardware, the N222331 serves as a load-distributing bearing plate in mechanical fastening assemblies. Plumbers, pipefitters, HVAC technicians, and general mechanical contractors install these plates as part of pipe hanging, conduit support, and equipment mounting applications where a secure, corrosion-resistant connection point is required.

This U bolt plate is suited for residential and light commercial applications where square U bolts are used to secure pipe, conduit, or structural components to a surface. It is specifically designed for use with model No. 2192 square U bolts. The zinc finish makes it appropriate for installations in areas with moderate moisture exposure. Each plate is sold individually, with a minimum order quantity of 10 units per order.
