Gibraltar GIB53620 Round U-bolt 3/4 Inch Pipe Steel

Product Description

The GIBRALTAR GIB53620 is a round U-bolt with a mount plate designed to secure 3/4-inch pipe to structural surfaces in mechanical, plumbing, and HVAC installations. The U-bolt features a 1/4-20 UNC thread with a 1-inch thread length, and is fabricated from C-1010 steel with a hot-galvanized finish for corrosion resistance. Two hex nuts are included for immediate installation. At 0.09 pounds, it is a lightweight hardware component suited for overhead, wall, or panel mounting applications where a stable pipe clamp with a backing plate is required. Licensed plumbers, pipefitters, and mechanical contractors are the primary installers of this type of hardware.

This U-bolt is used to anchor 3/4-inch nominal pipe runs in residential and light commercial mechanical systems, including HVAC refrigerant lines, water supply piping, and general conduit or tubing support. The mount plate distributes clamping load across the mounting surface, reducing stress on thin substrates such as sheet metal panels or light framing. The 2-inch overall length and 1-1/8-inch interior width conform to standard 3/4-inch pipe outside diameter clearances. It is appropriate for both interior and exterior installations where galvanized corrosion protection is adequate for the environment.

Compatibility

Designed as a standard pipe support fitting for 3/4-inch nominal pipe runs in plumbing, HVAC, and mechanical piping applications.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or HVAC technicians. Shut off fluid or refrigerant flow and depressurize the line before positioning clamps on active systems. The mount plate should be fastened to a structurally sound substrate using appropriately rated fasteners. Follow IPC or IFGC pipe support spacing requirements for the pipe material and application being served.
