Abstract
Abstract A self locking door light molding for use with doors of steel or other construction wherein it is desired to mount glass in a door light opening. The molding incorporates a peripheral exterior frame member and a matching, peripheral interior frame member, the said exterior and interior frame members projecting inwardly about the door light opening for glass holding purposes. Both the interior frame member and exterior frame member include matching facing, locking surfaces of saw tooth configuration which extend about the periphery of the opening. A plurality of horizontal locking members space about the periphery of the door light opening and incorporate saw tooth construction of size and design to cooperate with and lock upon the locking surfaces of the interior and exterior frame members in a manner to secure the frame members together interiorly and exteriorly of the glass insert and to prevent disassembly of the respective frame members.
