Installation Procedure

1. Position the U-bolt around the 3" pipe, ensuring it is centered and parallel to the pipe's run. 2. Insert the threaded legs through the mounting surface or bracket, aligning them with the pre-drilled holes. 3. Securely fasten the U-bolt using appropriate washers and nuts (not included), tightening evenly on both sides to achieve firm support without over-compression.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the nuts, which can deform the nylon material and reduce its vibration dampening capabilities.Tighten nuts until snug and the pipe is securely held, but avoid excessive force that could visibly distort the U-bolt.
Using the wrong size U-bolt for the pipe, leading to a loose fit or potential damage.Verify the nominal pipe size and compare it with the U-bolt's Inside Width (A) to ensure a proper fit.

Common Applications

  • Chemical processing pipe support
  • Marine and offshore installations
  • Electrical conduit and cable tray mounting

⚠️ Engineering Warnings

  • Not intended for structural load-bearing applications where significant mechanical stress is present.
  • Maximum operating temperature of nylon should be considered for high-heat environments.
