Gibraltar GIB53089 Round U-bolt 3/8-16 Unc 2 Inch Pipe Steel

Product Description

The GIBRALTAR GIB53089 is a round U-bolt designed to secure 2-inch pipe in mechanical, plumbing, and industrial support applications. Threaded to the 3/8-16 UNC standard with a 1-1/4 inch thread length and an overall length of 3-1/8 inches, this fastener is formed from C-1010 steel and finished with a hot-galvanized coating for corrosion resistance. Two nuts are included for immediate assembly. The 2-1/2 inch width accommodates standard 2-inch pipe outside diameter. Plumbers, pipefitters, and mechanical contractors install this type of hardware during pipe support and strapping work on both new construction and retrofit projects.

This U-bolt is suited for pipe support installations in residential and commercial mechanical systems where a 2-inch nominal pipe size requires a round-bend fastening point without a mount plate. It is appropriate for use in plumbing, HVAC piping, and general mechanical contractor applications where UNC-threaded steel hardware and a hot-dip galvanized finish are specified. The absence of a mount plate makes it compatible with direct-to-structure or customer-supplied bracket installations.

Key Features

• Round bend profile fits 2-inch nominal pipe outside diameter
• 3/8-16 UNC thread standard with 1-1/4 inch thread length for secure nut engagement
• Hot-galvanized finish provides corrosion resistance for wet and outdoor environments
• C-1010 steel construction for dependable mechanical strength
• Includes two nuts — ready to install without additional hardware
• Without mount plate — pairs with customer-supplied strut, bracket, or structure

Compatibility

Designed as a standard round U-bolt replacement or new-installation fastener for 2-inch nominal pipe support applications requiring a 3/8-16 UNC threaded steel fitting without a mount plate.

Installation Notes

Plumbers, pipefitters, and mechanical contractors typically install pipe U-bolts as part of a support system per applicable plumbing and mechanical codes. Shut off the system and relieve any pressure before working on or near live piping. Use appropriately sized wrenches to tighten the included nuts evenly on both threaded legs to avoid cocking the U-bolt on the pipe. Verify that the support spacing and hardware sizing comply with local code requirements for the pipe material and application.
