Cattle Corral with curved single-file chute (race) and round crowd pen. The fence posts are all 2-7/8-inch (7.30cm) O.D. used oil field pipe. In the areas with solid fence, the maximum distance between the fence posts is 4-feet (1.2m). Space posts no more than 8-feet (2.5m) apart in areas of the corral where the fence is not solid. The raised concrete platform on the inside radius of the single file chute (race) saves walking distance from the squeeze (crush) chute to the crowd pen.
