East's tarp storage box saves time and improves safety option on drop deck trailers. The unit can be built into the floor of the upper or lower deck. This on-deck access location reduces multiple ups and downs on the trailer (lessening the chance for falls) to tarp the load, or store the tarp and tie-downs, which saves time and energy for both tasks. Dimensions of the upper deck storage boxes come 35" long x 13" wide (maximum 22" deep). Lower deck box dimensions come 49 1/2" long x 42 1/2" wide (maximum 21" deep).
