The TRUE E810804 refrigerator door gasket in black measures 28-1/8" wide by 54-1/8" and is designed as a replacement seal for compatible units. It works by pressing firmly against the cabinet frame when the door closes, while an integrated magnetic strip helps keep the gasket securely aligned to minimize air gaps. By reducing warm air infiltration and preventing cold air loss, it supports consistent internal temperatures. Benefits include improved energy efficiency, reduced compressor workload, enhanced food preservation, and straightforward installation, making it a practical solution for maintaining dependable refrigeration performance in commercial environments.
