RAIL-MULLN W11455378

This genuine OEM vertical mullion rail assembly is designed for select French door refrigerators and helps ensure a proper seal by closing the gap between the two fresh-food doors. It attaches directly to the door and often includes an integrated heater that helps reduce condensation in humid conditions. Constructed for reliable, long-term performance, this assembly is engineered to match the original fit and function of the unit it replaces. Its size is consistent with standard French door mullion rails, making it a suitable replacement when the original component becomes worn, loose, or damaged, helping restore efficient sealing and overall refrigerator performance.
