Installation Procedure

1. Position the U-bolt around the 4" pipe, ensuring it straddles the pipe securely. 2. Place the U-bolt legs through the mounting surface or bracket, aligning with pre-drilled holes if applicable. 3. Securely fasten the U-bolt using two 1/2"-13 nuts (not included) and appropriate washers, tightening them evenly to achieve firm support without overtightening.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong size U-bolt for the pipe diameter.Always verify the pipe's nominal outer diameter and consult the U-bolt's inside dimensions (Width A and Length B) to ensure a proper fit.
Insufficient or uneven tightening of the securing nuts.Tighten nuts evenly on both legs of the U-bolt to distribute load and prevent pipe movement or damage. Use torque specifications if available for the application.

Common Applications

  • Marine applications requiring corrosion resistance
  • Plumbing and HVAC systems in corrosive environments
  • Support for offshore piping and infrastructure

⚠️ Engineering Warnings

  • Ensure compatibility of mating hardware (nuts and washers) with brass to prevent galvanic corrosion.
  • Do not exceed the product's stated load capacity; consult engineering specifications for specific load ratings.
