The 3-Shelf Super Shelf Truck is constructed of 14-ga. steel for rugged durability, and comes with a rubber shelf mat for secure load transport. The 24" x 36" top shelf of both 2- and 3-shelf models can be flipped to provide either a flush loading surface or a 1 1/2" lipped tray. Shelves are spaced 19 1/2" apart for optimum loading area. Trucks are mounted on 8" x 2 1/2" pneumatic tires for easy rolling over virtually any surface. Both models have a 1600-lb. overall capacity. Ships knocked down in 2 separate boxes.
