System One™ makes racks in various lengths and heights for service/utility body trucks and they are offered in both standard and I.T.S.® series. These racks are usually mounted to our Utility Traks for increased rigidity and tie-down capability. In bodies with top-opening compartments where the stationary ledge near the hinge is often too narrow to mount the Utility Traks, our "B Trak" is usually the solution. Body to roof height varies among these trucks so we stock legs of varying lengths from 12" up in 2" increments. Utility Traks are available in lengths of 8', 9' and 11' to accommodate various body lengths. Our Extension Beams (for Contractor Rigs™) are available in lengths of 102", 120", 138", 147", 156" and 174" for various cab/body combinations.
