Installation Procedure

1. Position the U-bolt around the 3" pipe, ensuring it rests snugly within the pipe's outer diameter. 2. Place the provided or compatible backing plate (if applicable) against the mounting surface. 3. Secure the U-bolt by threading the nuts onto each leg, tightening evenly to achieve firm, but not overtightened, pressure against the pipe and mounting surface.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Selecting the wrong U-bolt size for the pipe's actual outer diameter.Always measure the pipe's outer diameter to ensure a proper fit. Nominal pipe sizes can differ from actual dimensions.
Using standard carbon steel U-bolts in corrosive environments.Opt for 316 stainless steel for superior corrosion resistance in marine, chemical, or high-humidity applications to prevent premature failure.

Common Applications

  • Marine piping and conduit support
  • Chemical processing equipment mounting
  • Food and beverage industry installations
  • Plumbing and HVAC pipe securing

⚠️ Engineering Warnings

  • Ensure proper torque is applied during installation to avoid damaging the pipe or the U-bolt.
  • Verify compatibility of nuts and washers with the 1/2"-13 thread size and the 316 stainless steel material to prevent galvanic corrosion.
