This part is the replacement drawer slide rail for your refrigerator. It is made of white plastic and is approximately 16 inches long and 1.5 inches wide. The crisper draw 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 drawer 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.
