Gibraltar GIB53641 Round U-bolt 3/4 Inch Pipe Steel

Product Description

The GIBRALTAR GIB53641 is a round U-bolt with mount plate designed to secure pipe to structural surfaces in plumbing, HVAC, and mechanical piping installations. Threaded to a 5/16-18 UNC standard with a 1 inch thread length, this U-bolt fits 3/4 inch pipe and arrives with two nuts included for immediate installation. The body is fabricated from C-1010 steel with a hot galvanized finish, providing corrosion resistance in damp or outdoor mechanical environments. At 0.15 pounds, it is a compact, lightweight fastener suited for high-volume rough-in work. Licensed plumbers, pipefitters, and HVAC technicians regularly specify this type of fitting when hanging or securing copper, iron, or galvanized pipe runs.

This U-bolt is appropriate for residential and light commercial plumbing, hydronic heating, and HVAC refrigerant or condensate line support applications. The round shape conforms to standard pipe ODs, and the integrated mount plate simplifies attachment to unistrut channel, structural steel, or wood blocking. It is sized for 3/4 inch nominal pipe and is a common choice when fastening supply lines, drain lines, or gas piping where a secure, corrosion-resistant hold is required.

Key Features

• Round U-bolt shape with integrated mount plate for direct structural attachment
• 5/16-18 UNC thread standard with 1 inch thread length
• Sized for 3/4 inch nominal pipe
• C-1010 steel construction with hot galvanized finish for corrosion resistance
• Includes two nuts for complete, ready-to-install assembly
• Width of 1-1/8 inches and overall length of 2-3/16 inches for compact fitment

Compatibility

Designed for use with 3/4 inch nominal pipe in standard plumbing, HVAC, and mechanical piping support applications where a round U-bolt with mount plate is specified.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or HVAC technicians following applicable mechanical and plumbing codes. Shut off fluid flow and depressurize the line before repositioning or replacing any pipe support hardware. Ensure the mount surface is structurally adequate for the load and that fastener torque is applied evenly across both nuts to avoid distorting the pipe. Hot galvanized fasteners should not be used in contact with materials that may cause galvanic corrosion without appropriate isolation.
