The Ultimate Strength Series is the best in American technology. This new 2U version has been added to complete the line up of Ultimate Series racks. With its roto molded tough shell, front and rear lids, recessed heavy-duty twist latches, molded in handles, shock absorbing rubber feet and the recognizable patented deep Roto-X pattern for solid stackability, these cases provide maximum protection. The unique molded-in unbendable valance and steel threaded rails make the Ultimate Strength Series Roto-Racks the new professional standard in the industry.
