Gibraltar GIB51465 Round U-bolt 1/4-20 Unc for 3/4 Inch Pipe

Product Description

The GIBRALTAR GIB51465 is a round U-bolt designed to secure 3/4-inch pipe to structural supports in mechanical, plumbing, and HVAC piping systems. Threaded at 1/4-20 UNC with a 2.5-inch thread length, it provides a secure clamping grip without the need for a mount plate. Constructed from C-1010 steel with a zinc-plated finish, it resists corrosion in typical indoor mechanical room and light commercial environments. Four nuts are included, allowing installation directly from the package without sourcing additional hardware. Licensed plumbers, pipefitters, and HVAC technicians rely on this hardware for pipe support and routing applications.

The GIB51465 is suited for residential and light commercial pipe support installations where 3/4-inch pipe must be anchored to unistrut, framing, or structural members. Common applications include domestic water supply lines, refrigerant line routing, gas piping support, and HVAC branch piping. The open round shape accommodates standard 3/4-inch nominal pipe and provides uniform clamping force around the pipe diameter.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or HVAC technicians. Ensure the pipe is properly supported and aligned before tightening the U-bolt nuts evenly on both sides to prevent uneven loading. Follow applicable IPC, IFGC, or IMC requirements for pipe support spacing and fastener sizing. Do not overtighten, as this may deform the pipe or strip the threads on this lightweight hardware.
