Gibraltar GIB53647 Round U-bolt with Mount Plate 1 in Pipe

Product Description

The GIBRALTAR GIB53647 is a round U-bolt with a mount plate designed to secure 1-inch pipe in mechanical, plumbing, and HVAC piping support applications. Manufactured from C-1010 steel with a hot galvanized finish, this U-bolt resists corrosion in wet and outdoor environments. The 5/16-18 UNC thread size and 2-inch thread length provide a secure clamping interface, and the included mount plate simplifies attachment to structural surfaces. Two nuts are included for immediate installation. The overall length of 3.625 inches and interior width of 1.375 inches are sized to match standard 1-inch pipe outside diameter. At 0.2 pounds, this is a lightweight, single-piece pipe support solution suited for residential and light commercial piping runs.

This U-bolt is intended for securing 1-inch nominal pipe to structural members such as framing, unistrut, or equipment panels. Typical applications include HVAC refrigerant line support, plumbing supply line anchoring, and gas piping restraint where a hot-dip galvanized steel fastener is required. The mount plate design allows direct surface mounting without a separate beam clamp or channel. Plumbers, pipefitters, and HVAC technicians commonly use this style of U-bolt during rough-in and equipment installation on both residential and light commercial projects.

Compatibility

Designed as an OEM-style pipe support fastener for 1-inch nominal pipe in plumbing, HVAC, and mechanical piping systems where a hot galvanized round U-bolt with mount plate is specified.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or HVAC technicians following applicable local mechanical codes and IFGC or IPC requirements for pipe support spacing. De-energize or shut off the associated system before securing or repositioning any piping. Use a properly sized wrench to tighten the nuts evenly on both threaded legs to avoid cocking the U-bolt or damaging the pipe finish. Do not over-tighten on soft or coated pipe materials.
