Avantco 178SHELFUC48 Coated Wire Shelf - 20 13/16" x 17 1/16"

The vertical wire on the shelf should be positioned toward the back of the unit in order to allow space for proper air flow inside the cabinet. If the wire is installed to the front, items may block the flow of cold air along the back wall, causing products to reach unsafe temperatures or the refrigeration system to work harder to maintain a safe temperature.
