This is a great feeder that is deep enough to prevent spillage. Easily mounts in any stall with three steel eyelets built into the rim (additional mounting hardware not included). Also can be used on the ground or stall floor, where the wide, straight design makes a more stable feeder than conventional tapered buckets. Molded from a tough resin that is impact resistant and protects against warpage and stress cracks. This 32 Quart (8 gallon) feeder measures 18 1/2" long x 18 1/2" wide x 13 1/2" high
