The outer shell I6 is bent in a U-shape as shown at IE to form a pocket 2| whichextends completely around the door opening. The inner shell or food liner l-I islikewise bent .at right angles peripherally of the door opening I to form a flange 22 in the plane of the front of the cabinet and extending toward the flange I8 on the outer shell. A breaker strip nails is-dispensed with and which lies parallel to the front surfaces of the cabinet. Furthermore, the construction is readily assembled, neat in appearance, and provides an efiicient heat break and seal for the refrigerator cabinet.
