Gibraltar GIB53020 Round U-bolt 3/4 Inch Pipe Steel

Product Description

The GIBRALTAR GIB53020 is a round U-bolt designed to secure 3/4-inch pipe to structural surfaces without a mount plate. Manufactured from C-1010 steel with a hot galvanized finish, this fastener resists corrosion in wet and outdoor service environments. The 1/4-20 UNC thread pattern runs 1 inch in length, providing positive engagement with standard hex nuts. Two nuts are included. At 0.07 pounds, the GIB53020 is a compact, lightweight hardware item used by plumbers, pipefitters, HVAC installers, and general tradespeople wherever pipe needs to be anchored cleanly and quickly.

This U-bolt is suited for residential and light commercial piping applications. It fits 3/4-inch nominal pipe and is installed against flat structural members such as joists, strut, or framing without requiring a separate backing plate. The round bend profile conforms closely to the pipe OD, distributing clamping load evenly. Typical installations include domestic water supply lines, drain lines, refrigerant suction and liquid lines, and small-diameter gas piping where code allows this fastener type.

Installation Notes

Power down or shut off the relevant system before positioning pipe hangers on active lines. Install with a properly sized wrench or nut driver; do not overtighten, as this can deform the pipe wall or strip the 1/4-20 thread. Follow applicable codes — IPC, IMC, or IFGC — for maximum hanger spacing based on pipe material and diameter. A licensed plumber, pipefitter, or HVAC mechanic should verify fastener selection meets local code requirements.
