Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the nuts, which can deform the pipe or mounting surface.Use a torque wrench to tighten nuts to the manufacturer's recommended torque specification for the pipe size and mounting material.
Using the wrong size U-bolt, leading to a loose fit or inability to install.Always verify the nominal pipe size and measure the U-bolt dimensions (inside width and length) against the pipe and mounting requirements before purchase.
