ABSTRACT:
A door light having exterior and interior rectangular frames which are inserted into the door opening from opposite sides thereof. The exterior frame is molded of a plastics material as an integral, one-piece element having a rearwardly projecting tubular portion which slidably telescopes into a tubular portion defined by the interior frame. The interior and exterior frames slidably telescope until the flanges thereof abut the respective door faces to accommodate variable door widths. The exterior frame has a downwardly and forwardly sloped upper surface along the lower horizontal frame element which, in cooperation with an integral rear wall located behind the inner sash, causes all drainage along the sloped upper surface. Guide tracks are secured along the vertical sides of the frame and define outer and inner channels, with a top sash being stationarily fixed within the upper end of the outer channel.
