Thank you for your question regarding the Delta Adjustable Slide Bar / Grab Bar Assembly with Elbow. I will be happy to assist you today.
The mount for this slide bar hand shower is composed of a mixture of metallic and non-metallic materials. We manufacture most of our products like this for safety as well as the longevity of the model. Fully metallic products tend to rust over time and could potentially cause damage if dropped or if it falls.
I hope this information has answered your question. If you ever have any other questions, concerns, or require anything further please feel free to give us a call at 800-345-3358 and we will be happy to assist you in any way that we can.
Thank you again!
