Installation Procedure

1. Position the U-bolt around the 1" nominal pipe, ensuring it rests evenly on the pipe's exterior. 2. Secure the U-bolt by passing the threaded legs through the mounting surface and threading on the provided nuts and washers. 3. Tighten the nuts uniformly to achieve firm, secure support for the pipe, avoiding over-tightening which could deform the pipe or mounting surface.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Selecting the wrong U-bolt size for the nominal pipe diameter.Always verify the inside width (A) of the U-bolt against the actual outside diameter of the pipe being secured. For a 1" nominal pipe, the inside width is designed to accommodate its standard dimensions.
Using standard carbon steel U-bolts in corrosive environments.For marine, chemical, or outdoor applications, always specify 316 stainless steel to prevent premature rust and structural failure due to corrosion.

Common Applications

  • Marine hardware and rigging
  • Chemical processing pipe support
  • Plumbing and conduit clamping in corrosive atmospheres

⚠️ Engineering Warnings

  • Ensure compatibility of mounting hardware (washers, nuts) with 316 stainless steel to prevent galvanic corrosion.
  • Do not exceed the recommended torque specifications for the thread size to prevent damage to the U-bolt or mounting substrate.
