Installation Procedure

1. Position the U-bolt around the pipe, ensuring it rests evenly on the pipe's exterior. 2. Place the backing plate (if applicable) and thread the nuts onto the U-bolt legs, hand-tightening initially. 3. Torque the nuts to the manufacturer's recommended specification, ensuring even pressure on both sides to prevent pipe deformation.
