National Marker N222430 Stainless Steel Round U-bolt 5 Pack

Product Description

The NATIONAL MARKER N222430 is a stainless steel round U-bolt designed for secure pipe, conduit, and tube clamping applications. This assembly measures 0.25 inches in diameter, 1.125 inches in inner width, and 3.5 inches in length. Each pack includes five U-bolts, each with a mounting plate and two hex nuts, supplied pre-assembled for faster installation. The stainless steel construction resists corrosion in wet, outdoor, and chemically exposed environments, making this fastener a dependable choice for plumbing, mechanical, and structural clamping work performed by licensed tradespeople.

This U-bolt assembly is suited for residential and light commercial installations where a round-body clamp is needed to anchor pipe or conduit to a structural surface. The included plate and hex nuts eliminate the need to source separate hardware, which reduces staging time on the job. Typical applications include pipe support in mechanical rooms, conduit attachment to framing or strut, and general fastening tasks where corrosion resistance is a requirement.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or electricians depending on the application. Shut off flow or de-energize the system before securing any pipe or conduit clamps. Use appropriate hand tools to tighten hex nuts evenly and avoid over-torquing, which can deform the mounting plate or distort the pipe. Follow applicable IPC or NEC requirements for pipe and conduit support spacing.
