Gibraltar GIB53611 Round U-bolt 3/8 Inch Pipe Steel

Product Description

The GIBRALTAR GIB53611 is a round U-bolt with mount plate designed to secure 3/8 inch pipe in plumbing, HVAC, and mechanical piping applications. Manufactured from C-1010 steel with a hot galvanized finish, this fastener resists corrosion in damp and exposed environments. The 1/4-20 UNC thread pattern runs 1.5 inches in length, providing reliable engagement when paired with the two included nuts. With a total length of 2.25 inches and a width of 0.75 inches, this compact U-bolt is well suited for close-clearance mounting situations. Plumbers, pipefitters, and HVAC technicians install this type of hardware to anchor small-diameter pipe runs to structural members, hangers, and brackets.

This U-bolt is intended for use with 3/8 inch pipe in residential and light commercial mechanical systems. Typical applications include securing water supply lines, refrigerant tubing, and small-bore gas or pneumatic lines to framing, strut channel, or equipment panels. The included mount plate and two nuts allow for a complete installation without additional hardware, making it practical for service techs and installers working through high-volume rough-in or service calls.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or HVAC technicians in accordance with applicable mechanical and plumbing codes such as the IPC or IFGC. Shut off the relevant supply line and depressurize the system before repositioning or replacing pipe supports. Use appropriate hand tools to tighten the nuts evenly to avoid cocking the mount plate against the substrate. Do not over-torque the nuts on galvanized threads, as this can strip the coating and accelerate corrosion at the fastener joint.
