The Heritage Brass Charlston Door Knob on Lock Plate Satin Nickel is a stunning piece of door furniture; the backplate is identical to that of the Waldorf handle with its fan-like design. But the Charlston features a unique knob with a design that matches the backplate perfectly.  This door knob is made from solid brass and has a satin nickel finish - to help maintain the finish, periodically wipe over with a soft non-abrasive cloth moistened with soapy water and then use a dry cloth to buff gently to a shine. DO NOT USE Metal Cleaners or aerosol polishes as these will damage the surface...
