Installation Procedure

1. Position the U-bolt around the pipe, ensuring the pipe is centered within the U-bolt's curve. 2. Thread the nuts onto the U-bolt's legs, hand-tightening initially to align properly. 3. Tighten the nuts gradually and evenly, alternating between sides, to achieve the specified torque for secure pipe support.
