Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening the nuts, which can stress or deform the polycarbonate material.Tighten nuts until snug, then apply an additional 1/4 to 1/2 turn. Avoid excessive force.
Using metal washers that can cause galvanic corrosion or electrical conductivity issues.Always use the recommended polycarbonate or nylon washers provided with the U-bolt, or ensure compatible non-conductive washers are used.

Common Applications

  • Marine piping and conduit support
  • Chemical processing equipment mounting
  • Electrical conduit and cable tray securing
  • Plumbing in corrosive atmospheres

⚠️ Engineering Warnings

  • Ensure the application temperature range is within the material's specified limits (-40°F to 250°F).
  • Verify the 4.01" inside width is appropriate for the specific outer diameter of the 3" pipe being supported, accounting for any insulation or coatings.
