Installation Procedure

1. Position the U-bolt around the pipe, ensuring it rests evenly on the pipe's curvature. 2. Place the accompanying mounting plate or saddle beneath the pipe and align the U-bolt legs with the plate's pre-drilled holes. 3. Secure the U-bolt by threading the nuts onto the legs and tightening them evenly. Ensure the pipe is held firmly without over-compression.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using a U-bolt with incorrect dimensions for the pipe size.Always verify the U-bolt's inside width and length against the pipe's outer diameter and required clearance.
Inadequate tightening of the nuts, leading to slippage or instability.Tighten nuts firmly and evenly, using a torque wrench if specified for critical applications, to ensure a secure fit.

Common Applications
