The True E810810 refrigerator door gasket is a black replacement seal measuring 26-1/2" x 26-1/2", designed for compatible refrigeration units. It works by pressing firmly against the cabinet frame when the door closes, while its integrated magnetic strip secures the seal to prevent warm air from entering and cold air from escaping. This barrier supports consistent internal temperatures and proper food storage conditions. Benefits include improved cooling efficiency, reduced strain on the compressor, enhanced temperature retention, and straightforward installation, making it a practical solution for restoring reliable sealing performance in commercial refrigeration equipment.
