The lower end of the frame has a perimeter beam base, a raised floor and a pair of open-ended parallel fork tine tubes or sockets that communicate with the perimeter beam at the front and rear of the frame, preferably being structurally connected thereto. The frame includes a plurality of fixed side walls extending upwardly from the perimeter beam that include at least left and right side walls. A plurality of gates are movably mounted on the frame at least at the front and rear of the frame, the gates enabling a forklift to place loads on the floor. The frame has vertically extending positioning beams or lugs that segment the raised floor into a plurality of load-holding positions.
