The SKB iSeries Tool Tech Box with Pull Out Trays and Wheels features fold out dual trays with plastic dividers on both sides of the case with a clear covered middle section that can be snapped down to keep connectors and other small miscellaneous pieces in place. When the case is closed the fold-out trays sit on each other keeping the contents from shifting around. The storage area below the trays measures 20.5 inches by 3.375 inches for additional storage.
