Gibraltar GIB51530 Round U-bolt 3/8-16 Unc 2 Inch Pipe

Product Description

The GIBRALTAR GIB51530 is a round U-bolt designed for securing 2-inch pipe in mechanical, plumbing, and HVAC piping systems. Manufactured from C1010 steel with a zinc-plated finish for corrosion resistance, this U-bolt features 3/8-16 UNC threading with a 2-1/2 inch thread length. The round bend conforms to standard 2-inch pipe outside diameter. It ships without a mount plate and includes four nuts for complete installation. Weighing 0.33 pounds, it is a compact, reliable fastener used by plumbers, pipefitters, HVAC technicians, and mechanical contractors for pipe support and anchoring applications.

This U-bolt is suited for residential and light commercial piping installations where 2-inch pipe must be secured to structural members, strut channel, or similar supports. Typical applications include HVAC refrigerant line support, domestic water piping, and mechanical room pipe runs. The zinc plating makes it appropriate for indoor and mildly corrosive environments. Each unit is sold individually and arrives with all necessary nuts for a single mounting point.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or HVAC technicians. Isolate and depressurize any piping system before adjusting or installing pipe supports. Ensure the mounting surface or strut channel is rated for the load of the pipe and its contents. Follow applicable codes such as the International Plumbing Code or International Mechanical Code for pipe support spacing and fastener requirements.
