Installation Procedure

1. Position the U-bolt around the 3" pipe, ensuring it rests evenly on the pipe's outer surface. 2. Place the provided or compatible washers over the threaded ends of the U-bolt. 3. Thread the corresponding nuts onto the U-bolt, tightening them evenly and progressively until the pipe is securely clamped. Avoid over-tightening to prevent deformation.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using a U-bolt with insufficient inside width for the pipe's outer diameter.Verify the U-bolt's inside width (A) is at least 0.25" to 0.5" larger than the pipe's outer diameter to allow for secure clamping and insulation if needed.
Over-tightening the nuts, leading to deformation of the U-bolt or pipe.Tighten the nuts incrementally and evenly. Consult torque specifications if available for the specific application to prevent damage and ensure proper clamping force.

Common Applications

  • Marine pipe and conduit support
  • Lightweight structural framing
  • Chemical processing equipment installation

⚠️ Engineering Warnings

  • Ensure the material of the U-bolt is compatible with the environment to prevent galvanic corrosion if in contact with dissimilar metals.
  • Do not exceed the recommended load capacity for this U-bolt, as it may lead to failure.
