Gibraltar GIB53005 Round U-bolt 1/4-20 Unc 1/4 in Pipe

Product Description

The GIBRALTAR GIB53005 is a round U-bolt designed to secure 1/4-inch pipe to structural members without a mount plate. Threaded to a 1/4-20 UNC standard with a 3/4-inch thread length, it ships with two hex nuts ready for installation. The body is formed from C1010 steel and finished with a hot-dipped galvanized coating that provides corrosion resistance in exposed or outdoor service conditions. At 0.05 pounds, this is a compact fastener suited for light pipe runs in mechanical, plumbing, and HVAC support applications. The 9/16-inch inside width matches nominal 1/4-inch pipe OD for a secure, rattle-free clamp.

This U-bolt is used in residential and light commercial installations wherever 1/4-inch pipe must be anchored to unistrut, framing, or structural steel without a backing plate. Typical applications include refrigerant line support, small-diameter gas or water piping, and instrument tubing in mechanical rooms, utility chases, and rooftop equipment. Plumbers, HVAC technicians, and pipefitters reach for this fastener when hanging small-bore lines that require a clean, code-compliant anchor point. The hot-dipped galvanized finish makes it appropriate for damp or outdoor environments where plain steel would corrode prematurely.

Key Features

• 1/4-20 UNC thread standard with 3/4-inch thread length for positive nut engagement
• Round bend sized for 1/4-inch nominal pipe with a 9/16-inch inside width
• C1010 steel construction provides solid tensile strength for pipe support loads
• Hot-dipped galvanized finish delivers corrosion resistance in wet or outdoor service
• Includes two hex nuts — no additional hardware required for basic installation
• Mount-plate-free design installs directly through unistrut slots or drilled holes

Compatibility

Designed for use with 1/4-inch nominal pipe across standard mechanical, plumbing, and HVAC pipe support applications where a round U-bolt without a mount plate is specified.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or pipefitters following applicable mechanical and plumbing codes. Shut off and depressurize any pipe being worked on before fitting the U-bolt. Thread both included nuts evenly and snug to hand-tight before final tightening to avoid cocking the U-bolt on the pipe. Do not overtighten on thin-wall tubing, as deformation can restrict flow or compromise the line.
