This black frame factory window style shower door is designed for rectangular showers.  It features a full-divided lite hinged swing shower door centered between 2 adjacent side panels and a perpendicular 90 degree return panel. The matte black frame finish and external black metal mullions are arranged in a horizontal gridded window style design.  NOTE: The enclosure size options should be based of centerline dimensions and not the shower pan size. When selecting opening sizes please choose the option that matches your centerline dimensions for width and depth.
