Solid Material: The extension arm is made from solid brass, which ensures your shower experience is durable and enjoyable. It is strong enough to hold your fixed shower head however you want and do not need to worry about dropping it while you are adjusting the angle. Chrome Finish: The high end electroplating we applied on all of our Singing Rain products makes sure that it can resist 200 hours of salt spray test and keep you away from a rusty bathroom. The finish can be easily cleaned with simple touches and will keep shining as new.
