Abstract: A plurality of spring tubes is provided in an assembly to make a worker's practice of “pearl diving” unnecessary. A container has one tube attached in each corner and each tube has an internal coil spring secured at a bottom of an inner chamber but extended by a cable looped over a pulley at a top of the tube. A shelf or false bottom is attached to a quick link at an end of the cable in each tube. Each link is guided in a vertical slot formed in an outer chamber of each extruded plastic tube so that the shelf is spring-loaded and weight-responsive. A key advantage of the adjustable shelf is that it prevents back strain and similar muscular injuries to workers who are constantly leaning and bending over to retrieve or store articles in the container. The ability of the shelf to tilt at any or all corners allows it to float and not bind as product is loaded or removed. These tubes and the shelf can be adapted to any of the presently manufactured containers or racks.
