This Avantco 17819554 left hinged solid door is a direct replacement for the one that came standard on Avantco ZPT-36-FB and SS-PT-36 refrigerated sandwich prep tables. The door is a vital part of your unit, allowing a tight seal that locks in cold air. 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.
