Abstract
Foam plastic is injected into a hollow space between the inner and outer skin of a refrigeration unit. Contained in the foam plastic are metal plates positioned at points where walls, dividers or shelves may be attached to the refrigeration unit. The foam plastic hardens around the metal plates. Self taping screws drill through the skin, foam plastic and plate to rigidly attach structure being supported to the plate with a minimum amount of heat transfer through the foam plastic and metal plates.
