Abstract
Abstract A refrigerator freezer compartment has an evaporator forward of its rear wall for maintaining the freezer compartment at the desired temperature with a cover forward of the evaporator to define the rear of the freezer compartment within which food may be stored. A side ladder is attached to each side wall of the freezer compartment. A horizontal bar extends between the bottoms of the two side ladders to which it is attached and is secured to the bottom of a center ladder. The upper end of the center ladder may be supported within a nipple supported by the top wall of the freezer compartment or secured to a horizontal bar extending between the tops of the two side ladders and secured thereto. Each of the side ladders and the center ladder has a column of rectangular shaped slots to receive portions of an adjustable shelf so that one shelf may be mounted between one of the side ladders and the center ladder and another shelf may be mounted between the other side ladder and the center ladder. This insures alignment of all of the slots in the side ladders and the center ladder.
