The TRUE 932586 Refrigerator Wide Black Door Gasket maintains a secure seal around compatible refrigerator doors for proper temperature retention. Measuring 27-1/4" X 29-1/2", this gasket limits warm air from entering the cabinet when the door is closed. It works by creating a tight barrier between the door and refrigerator frame, reducing cold air loss. https://partsfe.com/door-gasket-for-true-part-932586
