Lakeside 448 Six Shelf Open Tray TruckLakeside Manufacturing engineered the 448 so you could easily transport trays from one area to another. This tray truck has an open design with eight shelves, each measuring 35 wide and 21 deep. Each shelf has three edges so trays dont get knocked off during transport. One side has a downturned edge for easy loading. The 448 has a non mark cushion tread on each of its 5 casters to absorb impact. This allows for a quieter and smoother operation.
