Abstract
A cage door construction, useful for poultry cages and the like which are stacked one above another, has a door opening framed in a wall of the cage by vertical and horizontal wires. The vertical wires extend beyond the upper horizontal wire of the door frame and are bent over to become part of the top of the cage where they serve as guide wires for sliding movement of the cage door. The case door is formed of a single piece of wire bent into a U-shaped with lateral arms extending outward from the open end therof. Each laterally extending arm is provided at its end with an eye which slidably engages one of the guide wires. Indentations, formed in the legs of the U-shaped door, can lock into place under the upper horizontal wire. When closed, a portion of the U-shaped door slides in front of and is then bent under a wire disposed below the door frame; it thus travels downward, being engaged in an entrapment below the door to restrict its sideward movement.
