May be needed if you have a stall shower with a center mounted single lever water control knob that is mounted higher up to where the WaterStick may hang down in front of it. This usually isn’t needed with a tub shower since the faucet controls are mounted low enough to not interfere with the WaterStick being able to hang unobstructed. The Offset Connector will offset the WaterStick 4″ to either side. (See the Specifications section for the WaterStick for measurements.) Includes a jumbo-sized suction cup with loop to attach to your shower wall and a nylon zip tie to wrap around the WaterStick body and through the suction cup’s loop to keep the WaterStick hanging straight. Note: The suction cup does not support the weight of the WaterStick and does not adhere well to porous surfaces.
