Abstract: A storage module for adjustable disposition within a cavity, bounded by opposed side walls, of a refrigerator unit. The module being secured therein by a spaced array of complimentary fixturing projections and fixturing cavities which are oriented angularly upwardly. The fixturing projections and fixturing cavities being arranged for selective mating engagement therebetween and positional restraint of the module in a predetermined location within the cavity. The fixturing projections and fixturing cavities being stabilized by a tribiological interface along at least a portion of the mating surfaces between the projections and cavities to restrain the module against dislodgment forces. The projections and cavities are tapered in the plane of movement of the module of each of the projections and cavities including an upper surface disposed at a first angle in the plane and a lower surface disposed at a second angle in the plane.
