The True E810810 Refrigerator Door Gasket helps maintain a tight door seal, supporting consistent cooling performance in commercial kitchen equipment. Measuring 26-1/2" x 26-1/2", this black gasket is designed to fit compatible True refrigeration units and create a secure barrier around the refrigerator door. It works by compressing against the cabinet frame when the door is closed, preventing cold air from escaping while limiting the entry of warmer outside air. This sealing action helps the refrigeration system maintain stable internal temperatures. Built for regular use in busy kitchens, the gasket supports energy efficiency, helps protect stored food items, and contributes to the reliable operation of professional refrigeration equipment.
