ABSTRACT:
In a door constructed of spaced apart skins mounted on a rectangular frame and reinforced with the core between the skins filled with a plastic foam, a window or door light frame system consists of a two part frame system with a window light permanently installed in one part of the system and the other part releasably adapted to register with the frame part with the window light installed during shipping and rotated when installed to bring the locking elements of the several parts into registry to permanently lock the frame system in an aperture formed in a door with stop means in the locking arrangements to prevent damage to the frame system or the door on which the frame system is installed from excessive compressive forces on the frame parts.
