This Avantco 17816557BLK right hinged door assembly is a direct replacement for the one that came standard on black GDW-49 and GDC-49 series units. The door is a vital part of your unit, allowing a tight seal that locks in cold air while still providing a clear view of the unit's interior. If the door is not closing properly, and replacing individual components is not an option, this part will give you a whole new door to ensure optimal performance.
