Irmi, what I have is for one of the single wide refrigerators. My new refrigerator came with only one shelf in the refrigerator part and none in the freezer. Thank goodness it has shelves in the doors. One of the old shelves fit in the freezer and I made a shelf using the wire shelving you can buy at Lowe's. I never could find a web site for the maker to order anything. I was so worried about finding something that would fit the space I didn't think to notice about the shelves. It will be an ongoing search for you to find parts.
