Installation Procedure

1. Position the U-bolt around the 4" pipe, ensuring the pipe rests securely within the U-bolt's curvature. 2. Align the threaded legs of the U-bolt with the mounting surface or bracket, and thread on the appropriate nuts and washers. 3. Tighten the nuts evenly and progressively to achieve a firm, secure fit, but avoid over-tightening to prevent material deformation.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using a U-bolt with incorrect pipe size or dimensions, leading to loose support or damage.Always verify the nominal pipe size and measure the required inside width and length before selecting a U-bolt.
Over-tightening nuts, which can cause stress cracking or deformation in the polycarbonate material.Tighten nuts gradually and evenly. Refer to torque specifications if available, and stop when the pipe is held firmly without excessive pressure.

Common Applications

  • Plumbing and Piping Support
  • Conduit and Cable Management
  • Structural Attachment and Bracing

⚠️ Engineering Warnings

  • Ensure the ambient temperature remains within the specified operating range of polycarbonate for optimal performance and longevity.
  • Inspect regularly for signs of wear, damage, or material degradation, and replace if compromised.
