Use this Avantco 17818909 left hinged bottom half door as a direct replacement for the one that came with your Avantco SS-2 half door refrigeration unit. Made of durable, type 430 stainless steel, this door is made to handle daily, rigorous use in a busy commercial kitchen. A self-closing mechanism automatically closes the door when it's open to 90 degrees or less, conserving energy and keeping the interior at a consistent temperature. When the door is positioned past 90 degrees, the stay-open feature keeps the door open for easy loading and unloading. Replace a worn or damaged door right away to ensure that the interior of your refrigeration unit is tightly sealed and your food items are held at the appropriate temperature.
