Metal door and light assembly

摘要

A metal door is provided with a rectangular opening the edges of which are bent to form a ledge. Two half-frame structures are formed from side members and corner pieces which snap into the side members and the half-frames are placed in the opening from opposite sides and held together by threaded fasteners so that the frame does not protrude beyond the door faces. A method of cutting the plates removed from the rectangular opening to obtain all material for side members, corner pieces and muntins is disclosed.
