Installation Procedure

1. Position the U-bolt around the pipe or conduit, ensuring it rests on a suitable mounting surface. 2. Thread the nuts onto the U-bolt legs until snug against the mounting surface. 3. Tighten nuts evenly to the recommended torque specification (refer to load rating chart for specific value), ensuring a secure but not over-compressed fit.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the nutsTighten nuts until the U-bolt makes firm contact with the mounting surface. Over-tightening can deform the nylon and reduce its load-bearing capacity.
Using the wrong size U-boltVerify the nominal pipe size and corresponding U-bolt dimensions (Inside Width A, Inside Length B) before installation to ensure a proper fit and secure support.

Common Applications

  • Plumbing and pipe support
  • Electrical conduit mounting
  • Marine and chemical processing
  • Automotive and industrial equipment

⚠️ Engineering Warnings

  • Not intended for use in environments exceeding 180°F (82°C).
  • Consult material compatibility charts for specific chemical resistance requirements.
  • Ensure proper torque is applied to avoid material fatigue or failure.
