This part is the replacement crisper pan slide rail for your refrigerator. It is made of white plastic and is approximately 13 inches by 2 inches. The crisper drawer will slide in and out along this rail. If the rail is damaged or missing, the crisper will either hang from one side, or it will not stay in place at all. The crisper slide rail is for the left side of the drawer only, so be sure to check that you are replacing the correct drawer rail. This part is sold individually and is an OEM part sourced directly from the manufacturer.
