Gibraltar GIB53617 Round U-bolt 1/2 Inch Pipe Galvanized

Product Description

The GIBRALTAR GIB53617 is a round U-bolt with a mount plate, designed to secure half-inch pipe to structural surfaces in plumbing, mechanical, and general trade applications. Fabricated from C1010 steel with a hot-dipped galvanized finish, it resists corrosion in wet and outdoor environments. The 1/4-20 UNC thread is 1.25 inches long, providing reliable clamping force with the included hardware. Two nuts are included. Overall length is 2.75 inches and width is 1 inch. At 0.11 pounds, it is a compact, single-package fastener suited for high-volume rough-in work where consistent, code-compliant pipe support is required.

This U-bolt is appropriate for residential and light commercial pipe support installations involving half-inch pipe runs. Typical applications include securing copper, CPVC, or steel pipe to framing, strut channel, or structural members. The integrated mount plate simplifies attachment to flat surfaces without additional hardware. Licensed plumbers and mechanical contractors use this type of U-bolt during rough-in phases of plumbing and HVAC piping work where pipe movement and vibration must be controlled per applicable code requirements.

Installation Notes

Installation is performed by licensed plumbers or mechanical contractors. Shut off water supply and depressurize the line before adjusting or repositioning pipe supports. Tighten nuts evenly to draw the U-bolt snug against the pipe without deforming the pipe wall. Verify pipe support spacing complies with the applicable edition of the International Plumbing Code or local mechanical code for the pipe material in use.
