Ceiling-mounted BOOMs have a 5 ft. 6 in. arm with full 360-degree rotation that allows operators to wash cars without dragging the hose on the ground. Perfect for the initial washing before car wash tunnels, as well as washbays in general, hose hangs down from the arm and never contacts the ground. Simply swing the arm to the side and place the gun in a stainless steel wand holder when done washing.
