Installation Procedure

1. Position the U-bolt around the pipe, ensuring it rests evenly on the pipe's exterior. 2. Place the provided backing plate (if applicable) and thread the nuts onto the U-bolt legs. 3. Tighten the nuts alternately and evenly to achieve snug contact, avoiding over-tightening that could distort the polycarbonate.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the nuts, causing stress fractures in the polycarbonate.Tighten nuts gradually and alternately, stopping when the U-bolt makes firm contact with the pipe and mounting surface.
Using the wrong size U-bolt for the pipe diameter.Verify the Inside Width (A) matches or slightly exceeds the outer diameter of the pipe to be secured.

Common Applications
