Tighten Shower Arm with Pliers' Handles (Scratch-Free)

What happens here

To achieve a final secure tightening without marring the new shower arm's finish, grab a pair of channel lock pliers. Crucially, do not use the metal jaws of the pliers directly on the shower arm. Instead, flip the pliers upside down and use the plastic or rubber-coated handles to apply leverage. Insert the handles into the open end of the shower arm and turn clockwise until the shower arm is fully tightened and positioned straight down, ready for the showerhead to be attached. This unconventional technique provides the necessary torque without damaging the polished surface.
