Abstract: Shelf supports in the form of slots are integrally molded within each side wall of a refrigerator liner. The slot in one sidewall is in the same horizontal plane as the slot in the other sidewall. The bottom surface of each of the slots supports a shelf. The slots include an upper surface and lower surface having at least one stop located therebetween and integrally molded with the sidewall in the slot for preventing movement in at least one direction. The liner, therefore, supports fixed shelves, pull-out shelves, cantilever half-shelves, as well as being capable for using with shelves which are supported at both sides by cantilevers such that if a different type of shelf replaces the shelf held on both sides by cantilevers, the liner may be used.
