Gibraltar GIB51735 Round U-bolt 1/2-13 Unc Stainless Steel

Product Description

The GIBRALTAR GIB51735 is a round U-bolt designed to secure pipe to structural supports in mechanical, plumbing, and industrial installations. Built from 304 stainless steel, it delivers corrosion resistance suited for wet, outdoor, or chemically exposed environments. The U-bolt features a 1/2-13 UNC thread with a 3-inch thread length and is sized to fit 2-1/2 inch pipe. It ships with four nuts included, making it ready to mount without additional hardware. Licensed plumbers, pipefitters, and mechanical contractors use this type of hardware when installing or supporting pipe runs in both new construction and retrofit applications.

This U-bolt is appropriate for residential and commercial pipe support applications where a round, clamp-style fitting without a mount plate is required. The 2-15/16 inch width and 5-7/32 inch length make it compatible with standard 2-1/2 inch pipe runs. It is commonly installed along structural members, joists, or threaded rod hangers where direct clamping to the support surface is preferred over a plated mount configuration.

Key Features

• 304 stainless steel construction provides corrosion resistance in wet and outdoor environments
• 1/2-13 UNC thread with 3-inch thread length for secure fastening through structural members
• Sized for 2-1/2 inch pipe without a mount plate for direct structural attachment
• Includes four nuts for complete installation without additional hardware
• Round shape provides even clamping pressure around the pipe circumference

Compatibility

Designed as a standard round U-bolt for 2-1/2 inch pipe support applications. No mount plate is included, making it suitable for installations where the U-bolt threads directly through a structural surface or support channel.

Installation Notes

Installation is typically performed by licensed plumbers or pipefitters following applicable mechanical and plumbing codes. Power down or depressurize the pipe system before repositioning or replacing pipe supports. Ensure the support structure can handle the load of the pipe and its contents before final torque. Use appropriate wrenches on the included nuts and verify thread engagement on both legs before tightening.
