Gibraltar GIB51705 Round U-bolt 3/8-16 Unc 1/2 Inch Pipe Ss

Product Description

The GIBRALTAR GIB51705 is a round U-bolt designed to secure pipe runs in mechanical, plumbing, and industrial support applications. Built from 304 stainless steel, it resists corrosion in wet, outdoor, and chemically exposed environments. The bolt features a 3/8-16 UNC thread with a 2-3/8 inch thread length and an inner width of 15/16 inches, sized to fit 1/2 inch pipe. Each unit ships without a mount plate and includes four nuts, giving installers flexibility to select the appropriate backing plate for the specific substrate. Plumbers, pipefitters, and mechanical contractors install this type of hardware during pipe support framing and hangar work.

This U-bolt is suited for residential and light commercial pipe support applications where corrosion resistance is a priority. The 304 stainless steel construction makes it appropriate for exposed outdoor installations, coastal environments, and wet mechanical rooms. It fits 1/2 inch pipe, a common size in domestic water supply, gas distribution, and HVAC refrigerant line support work. The 3-inch overall length and 15/16 inch interior width provide a stable, secure wrap around standard 1/2 inch pipe OD. The four included nuts allow for double-nut locking on each threaded leg.

Installation Notes

This U-bolt is installed by licensed plumbers, pipefitters, or mechanical contractors in accordance with applicable codes such as the International Plumbing Code (IPC) or International Mechanical Code (IMC). Shut off fluid flow and depressurize the line before working on any pipe support assembly. Select a compatible mount plate or strut channel rated for the load before torquing the included nuts. Do not overtighten, as excessive clamping force can deform thin-wall pipe.
