Abstract: A horse stall gate manufactured from a lightweight polymer. The gate includes a plurality of ventilation slots designed to provide optimum airflow to the horse stall while only nominally reducing the strength of the gate, the slots being sized smaller than the horse's hooves. The gate is formed by rotational molding resulting in a hollow construction in the areas between ventilation slots and greatly reducing the weight. Rotational molding also produces a smooth exterior surface with rounded edges and corners to eliminate the chance of injury from sharps. The gate is reversible so that it may be hinged to either side of a stall doorway and includes a central indent in the upper edge for the horse to lean out of. Finally, the raw material can be provided in any color prior to rotational molding completely eliminating the expense and hazard of paint.
