The Annex shower rail system from Moen allows for the addition of a hand shower and slide bar to the current shower arm connection without changing the existing in-wall valve. The chrome-finish rail system works without any shower valve, shower arm, showerhead or hand shower. Features include a two-function diverter and 2 1/2-inch horizontal adjustability to accommodate varying wall thicknesses. 800/553-6636; www.moen.com.
