Abstract

A generally hollow plastic molded pen front provides multiple operating positions of the door having sets of interdigitating hinge knuckles on the door and door jamb on both the left and right side. The door also may be swung in or out, and one or more stops can be provided for any of four configurations—left hinged swing in; left hinged swing out; right hinged swing in; right hinged swing out. With the stops removed, the door may be swung both in and out. In one embodiment a J-shaped latching rod secures both the upper and lower portions of the door when latched and a J-shaped hinge rod cooperates on the other side and can use some of the same holes as the latching rod. In another embodiment, a pivoting handle works to secure the door in a catch channel for all six configurations. Other integrated features provide a choice of feed opening sizes and a guard that minimizes feed and water contamination.
