National Marker N222422 Stainless Steel Round U-bolt 5 Pack

Product Description

The NATIONAL MARKER N222422 is a stainless steel round U-bolt assembly designed for secure pipe, conduit, and tube clamping in trade and industrial applications. Each pack includes five U-bolts, a mounting plate, and two hex nuts per bolt, arriving pre-assembled for faster installation. The U-bolt measures 0.25 inches in diameter with a 1.125-inch inner width and 2.25-inch leg length. Constructed from steel with a stainless steel finish, this hardware resists corrosion in wet, outdoor, and chemically exposed environments. Plumbers, pipefitters, and mechanical contractors typically install this type of hardware when securing runs of pipe or conduit to structural supports.

This U-bolt assembly is suited for residential and light commercial applications where corrosion-resistant pipe support hardware is required. Common install scenarios include securing copper, PVC, or steel pipe to joists, unistrut, or equipment frames. The pre-assembled plate and nut configuration reduces staging time on the job. The pack quantity of five makes it practical for multi-point support runs or repeat fastening tasks on a single project.

Key Features

• Stainless steel finish provides corrosion resistance for wet and outdoor environments
• Comes pre-assembled with mounting plate and two hex nuts per U-bolt
• Pack of five units reduces per-unit handling time on multi-point installs
• Round bend profile suited for cylindrical pipe and conduit clamping
• Catalog series 2193BC for cross-reference ordering

Compatibility

Designed as a standard-style round U-bolt for securing pipe, conduit, or tubing to flat mounting surfaces in mechanical and plumbing support applications.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or general mechanical contractors. Ensure the mounting surface and support structure are rated for the load before fastening. Tighten hex nuts evenly to avoid distorting the U-bolt bend or crushing the pipe wall. Follow applicable IPC or local mechanical code requirements for pipe support spacing and hardware specifications.
