Installation Procedure

1. Position the U-bolt around the 4" pipe, ensuring the pipe is properly supported by a mounting surface. 2. Thread the provided nuts onto the U-bolt legs, hand-tightening initially to ensure proper alignment. 3. Tighten the nuts evenly in an alternating pattern to achieve a secure and stable fit, avoiding overtightening which can damage the pipe or mounting surface.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Selecting the wrong U-bolt size for the pipe's nominal diameter.Always verify the U-bolt's internal dimensions (Width and Length) against the actual outer diameter of the pipe and the required clearance for proper fit and support.
Using standard carbon steel U-bolts in corrosive environments.For applications exposed to moisture, chemicals, or saltwater, always specify 304 or 316 stainless steel for long-term corrosion resistance and structural integrity.

Common Applications

  • Pipe and conduit support in plumbing and HVAC systems
  • Securing tubing and structural members in marine and offshore environments
  • Vibration dampening and support for mechanical equipment

⚠️ Engineering Warnings

  • Ensure compatibility of thread size and pitch with mating hardware (nuts, washers, plates).
  • Do not exceed the specified load capacity of the U-bolt; consult engineering drawings or manufacturer specifications for load limits.
