Gibraltar GIB53011 Round U-bolt 3/8 Inch Pipe Steel

Product Description

The GIBRALTAR GIB53011 is a round U-bolt designed to secure 3/8-inch pipe in mechanical, plumbing, and HVAC piping applications. Manufactured from C1010 steel with a hot-dipped galvanized finish, it provides corrosion resistance in exposed or damp service environments. The fastener features 1/4-20 UNC threading with a 1.5-inch thread length and an overall length of 2.25 inches. Width across the U measures 0.75 inches. Two hex nuts are included for immediate installation without additional hardware. This style ships without a mount plate, making it suitable for applications where direct fastening to a structural element is required.

This U-bolt is used to clamp and support small-diameter pipe runs in residential and light commercial settings. Typical applications include securing copper, iron, or conduit runs to framing, strut channel, or structural supports during plumbing, HVAC, and mechanical rough-in work. The hot-dipped galvanized coating makes it appropriate for installations where moisture exposure is a factor, such as crawl spaces, mechanical rooms, and outdoor-adjacent environments.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or mechanical contractors during pipe support rough-in. Shut off the relevant system and relieve any line pressure before repositioning or retightening pipe supports. Use appropriately sized wrenches to snug the included nuts evenly on both threaded legs to avoid cocking the U-bolt on the pipe. Follow applicable local mechanical codes and IPC or IFGC support spacing requirements for the pipe material and size being secured.
