(High Country Plastics) Heavy insulation prevents water from freezing, allowing horses to drink regularly in an occupied stall. Unique design allows for watering with or without a bucket, and makes cleaning easy. Includes a 5 gallon bucket and a float. The float bowl helps insulate the buckets from the top by floating at or just below water surface. Horses can easily access the water by nudging the float which also helps keep the water circulating. When used as designed, water will remain unfrozen to approximately 15 degrees Fahrenheit.
