Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening nylon fasteners.Use a torque wrench and adhere to manufacturer-recommended torque values for nylon. Over-tightening can lead to material deformation or failure.
Using the wrong size U-bolt for the pipe.Always verify the nominal pipe size and corresponding U-bolt dimensions (Inside Width and Length) before installation to ensure a proper fit.

Common Applications

  • Plumbing and HVAC pipe support
