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 ShowerStick 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 ShowerStick being able to hang unobstructed. The Offset Connector will offset the ShowerStick 4″ to either side. (See the Specifications section for the ShowerStick 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 ShowerStick body and through the suction cup’s loop to keep the ShowerStick hanging straight. Note: The suction cup does not support the weight of the ShowerStick and does not adhere well to porous surfaces.
