Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening nuts, which can deform the pipe or strip threads.Tighten nuts to the recommended torque specification for the pipe material and application to ensure a secure fit without damage.
Using the wrong size U-bolt for the pipe diameter, leading to insecure or damaging fits.Always verify the pipe's outer diameter and select a U-bolt with the appropriate inside width (A) for a secure and compliant installation.

Common Applications

  • Securing rigid conduit and electrical conduit.
  • Supporting plumbing and HVAC pipework.
  • Anchoring structural steel and mechanical components.

⚠️ Engineering Warnings

  • Ensure proper thread engagement when tightening nuts to avoid cross-threading or stripping.
  • Inspect for corrosion or damage before installation to guarantee structural integrity.
