This rail is built of brass tube, li^ in. or 1^ in. indiameter, and is, of course, nickel plated. The tees ar^ of anornamental design and wall and floor flange connections areprovided for flow and return pipes. Where all four flanges arefixed to the wall the controlling valve is generally placed betweenthe wall flange and the rail and, of course, the flow may enterthe top rail instead of the bottom if preferred.
