Gibraltar GIB51730 Round U-bolt 3/8-16 Unc 2 Inch Pipe

Product Description

The GIBRALTAR GIB51730 is a round U-bolt designed to secure 2-inch pipe without a mount plate. Manufactured from 304 stainless steel, it offers corrosion resistance in wet, outdoor, and chemical-exposure environments. The fastener uses a 3/8-16 UNC thread with a 2.5-inch thread length and an overall length of 4.4375 inches. Width across the inside of the bend measures 2.4375 inches to match the outside diameter of standard 2-inch pipe. Four nuts are included. This type of hardware is installed by plumbers, pipefitters, HVAC technicians, and mechanical contractors wherever pipe support and clamping are required.

The GIB51730 is suited for use in residential and commercial mechanical systems where 2-inch pipe runs need to be anchored, supported, or clamped to structural members or equipment frames. The round profile conforms to the pipe surface, distributing clamping load evenly. The stainless steel construction makes it appropriate for outdoor installations, corrosive environments, marine applications, and anywhere carbon steel hardware would be subject to rust or chemical attack.

Key Features

• 304 stainless steel construction for corrosion resistance in wet and outdoor environments
• Round profile fits 2-inch nominal pipe securely without a mount plate
• 3/8-16 UNC thread standard for compatibility with widely available hardware
• 2.5-inch thread length provides adequate engagement depth for secure fastening
• Includes four nuts — no additional hardware required for basic installation
• Sold individually, allowing single-unit procurement for service and repair work

Compatibility

Designed for use with 2-inch nominal pipe and sized for installations requiring a round U-bolt without a mount plate in inch-measurement systems.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or HVAC mechanics as part of pipe support work. Shut off and depressurize the pipe system before repositioning or replacing any clamping hardware. Torque nuts evenly on both threaded legs to achieve uniform clamping force and prevent pipe distortion. Refer to applicable mechanical codes such as the International Plumbing Code or relevant ASME pipe support standards for required support spacing and fastener specifications.
