Installation Procedure

1. Place the U-bolt around the 4" pipe, ensuring it is centered on the desired support point. 2. Position the accompanying mounting plate or saddle beneath the pipe and align the U-bolt's threaded ends through the plate's holes. 3. Secure the U-bolt by threading the nuts onto the ends, tightening them evenly and progressively until the pipe is firmly held without deformation.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening the U-bolt, which can deform the pipe and compromise its structural integrity.Tighten nuts evenly and progressively, checking for pipe deformation. Use a torque wrench if specific torque values are required for the application.
Using a U-bolt with incorrect dimensions for the pipe size, leading to a loose or insecure fit.Always verify the U-bolt's inside width and length against the nominal pipe size and measure the actual pipe diameter if unsure.

Common Applications
