ABSTRACT OF THE DISCLOSURE An industrial storage rack construction which receives cassettes, that is, elongated racks for heavy materials, in vertically arranged relationship. The cassettes are to be in- serted in and retrieved from the rack, and the invention per- tains to the means for supporting the cassettes This means comprises a series of rollers from front to rear of the rack at each level, supported by anti-friction bearings, and a rigid bar with a convex upper surface across the rear of the rack. The top of this bar is at a level slightly above the level of the rollers. Each cassette is constructed with lower rails which ride on the rollers when the cassette is being inserted. The rearward ends of these rails will ride up on the rigid bar as insertion is completed so that the cassette will be frictionally locked in place while still being retrievable by the exertion of a relatively small withdrawing force. The friction lock will prevent creeping of the cassette out of its bay, and in case of seismic shocks the storage rack will tend to shift under the loaded cassettes, minimizing stresses on the storage rack itself.
