Installation Procedure

1. Position the U-bolt around the 3" pipe, ensuring it is centered. 2. Thread the nuts onto the U-bolt legs, hand-tightening initially. 3. Use a calibrated torque wrench to tighten the nuts evenly to the recommended torque specification for the thread size and application to prevent pipe deformation and ensure secure fastening.
