Gibraltar GIB53644 Round U-bolt 5/16-18 Unc 1 Inch Pipe

Product Description

The GIBRALTAR GIB53644 is a round U-bolt with mount plate designed to secure 1-inch pipe to structural surfaces in mechanical, plumbing, and HVAC piping installations. Manufactured from C-1010 steel with a hot galvanized finish, this fastener resists corrosion in exposed or damp environments. The 5/16-18 UNC thread pattern and 1-inch thread length provide solid clamping engagement, and the included pair of nuts allows for immediate installation without sourcing additional hardware. At 0.15 pounds, the GIB53644 is a lightweight but durable choice for pipe support applications requiring a clean, positive mount.

This U-bolt is suited for residential and light commercial piping systems where 1-inch nominal pipe must be anchored to framing, unistrut, or structural plate. Typical applications include HVAC refrigerant line support, domestic water supply piping, and general mechanical pipe runs. The mount plate configuration provides a broad bearing surface that distributes load and simplifies alignment during installation. Plumbers, pipefitters, and HVAC technicians routinely use this style of fastener when securing horizontal or vertical pipe runs to fixed structure.

Key Features

• Fits 1-inch nominal pipe with a 1-3/8 inch inside width
• 5/16-18 UNC thread with 1-inch thread length for reliable clamping depth
• C-1010 steel construction with hot galvanized finish for corrosion resistance
• Includes two nuts for complete, ready-to-install assembly
• Mount plate included for broad bearing surface and structural attachment
• Overall length of 2-3/16 inches suits standard pipe support spacing

Compatibility

Designed as an OEM-style replacement or standard-stock fastener for 1-inch pipe support applications in residential and commercial mechanical systems.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or HVAC technicians following applicable mechanical and plumbing codes. Shut off and depressurize the piping system before repositioning or replacing any pipe supports. Use appropriate wrenches to tighten the included nuts evenly on both threaded legs to avoid cocking the U-bolt against the pipe wall. Do not overtighten against copper or thin-wall pipe without a protective sleeve or liner where required by code.
