Gibraltar GIB53029 Round U-bolt 1/4-20 Unc 1 Inch Pipe Steel

Product Description

The GIBRALTAR GIB53029 is a round U-bolt designed to secure 1-inch pipe in mechanical, plumbing, and HVAC support applications. Manufactured from C-1010 steel with a hot galvanized finish, it provides corrosion resistance in both indoor and outdoor service environments. The 1/4-20 UNC thread pattern runs 1.375 inches in length, and the bolt spans 2.75 inches in overall length with a 1.5-inch inner width to fit standard 1-inch nominal pipe. Two hex nuts are included. This fastener is installed by plumbers, pipefitters, HVAC technicians, and mechanical contractors as part of pipe support and hanging assemblies.

This U-bolt is suited for use in residential and light commercial mechanical systems where 1-inch nominal pipe must be anchored to structural members, unistrut channel, or framing. Common applications include copper, steel, or plastic supply and return lines, refrigerant piping hangers, and general mechanical pipe support work. The hot galvanized coating makes it appropriate for damp or exposed locations such as crawlspaces, mechanical rooms, and outdoor pipe runs where bare steel would corrode.

Installation Notes

Install by licensed plumbers, pipefitters, or HVAC technicians in accordance with applicable mechanical codes such as the IPC or IFGC for pipe support spacing requirements. Shut off and depressurize the pipe system before repositioning or replacing any support hardware. Do not overtighten the hex nuts against plastic or thin-wall tubing without appropriate insulation inserts or cushion liners. Confirm compatibility with the existing support channel or mounting surface before installation.
