Installation Procedure

1. Position the U-bolt around the 3" pipe, ensuring the pipe is centered within the U-bolt's inside width. 2. Place the U-bolt over the mounting surface or support structure, aligning the threaded legs with pre-drilled holes or mounting points. 3. Secure the U-bolt using appropriate nuts and washers (sold separately), tightening them evenly to achieve the required clamping force without over-stressing the components.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using undersized or incorrect thread fasteners.Always use the specified 1/2"-13 UNC nuts and washers to ensure proper thread engagement and secure fastening.
Over-tightening the nuts, leading to deformation of the pipe or support structure.Tighten nuts evenly and progressively to the recommended torque specification for the application, ensuring a snug fit without excessive force.

Common Applications

  • Heavy-duty pipe suspension and support
  • Structural mounting for conduit and cables
  • General purpose fastening in industrial environments

⚠️ Engineering Warnings

  • Ensure compatibility of nuts and washers with the 1/2"-13 UNC thread size.
  • Do not exceed the load-bearing capacity of the U-bolt or the mounting structure.
