Product Description

The NATIONAL MARKER N222448 is a stainless steel round U bolt sold in a 5-pack, designed for securing pipe, conduit, tubing, or rod to a structural surface. Each assembly includes a backing plate and two hex nuts, arriving pre-assembled and ready for installation. The U bolt measures 5/16 inch in rod diameter, 1-3/8 inch in inside width, and 2-1/2 inch in inside length. The stainless steel finish provides corrosion resistance in wet, outdoor, or chemically exposed environments.

This U bolt assembly is suited for residential and light commercial applications where pipe or conduit must be anchored to a mounting surface such as a beam, strut, or wall plate.
