This 50' coil jockey box is offered in a cylindrical 8-quart cooler. The jockey box includes a 50-ft. 5/16" I.D. stainless steel coil and 2 ice box coupler assemblies. This coil cooler is designed for use with a clamp-on tower. A stainless steel coil is far superior for cooling than the "cold plates" style jockey box.
