From hauling skids of ice, storage of other refrigerated or frozen products to temporary or permanent cold storage, the 5 x 9 is very versatile. The standard transport is constructed to allow loading two 42 x 48 pallets of ice. Pallet skid rails, pallet stop and interior door kick plates help keep skids in place and protect the transport surface interior.
