Installation Procedure

1. Position the U-bolt over the 3" pipe and the mounting surface, ensuring the pipe is centered within the U-bolt's legs. 2. Thread the provided nuts onto the U-bolt legs, ensuring even initial engagement on both sides. 3. Tighten the nuts incrementally and alternately to achieve uniform clamping pressure. Avoid over-tightening, which can deform the pipe or mounting surface.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong size U-bolt for the pipe diameter.Always verify the pipe's nominal and actual outer diameter and select a U-bolt with an appropriate inside width (A) and length (B) to ensure a secure and stable fit.
Over-tightening the nuts, leading to deformation or damage.Tighten nuts evenly and incrementally. Consult torque specifications for the specific application and material if available to prevent over-stressing the components.

Common Applications

  • Marine pipe support and rigging
  • Industrial conduit and pipe securing
  • Lightweight structural framing and bracing

⚠️ Engineering Warnings

  • Ensure compatibility of thread size and material with mounting hardware (nuts and washers).
  • Aluminum 6061 has good corrosion resistance but may be susceptible to crevice corrosion in specific aggressive chemical environments. Assess suitability for your operating conditions.
