The Rolling shock mount case series incorporates our Black powder coated twist latches with locking loops and low profile injection molded pull handle with a 20 inch deep tough shell. The molded design provides extra stiffness in the lids and sides and allows for secure stacking. Rack depth front to rear rail is 20 inches and each lid is 2-1/4 inches deep. Rack rails are pre-threaded for standard 10-32 hardware and the mounting screws are included. Doors are fully usable even when racks are stacked together. Elastomeric shocks protect even the heaviest of loads. Sliding retractable handle, ambient pressure relief valve, oversized snap-down handles on each side, roller blade wheels, and gasket protected front and rear doors are all standard equipment.
