This Avantco 17817562 left hinged glass door is a perfect replacement for the one that came with select SS-2R-G-HC and A-49R-G-HC series units. It is a vital part of your unit's door assembly, working to create a firm door seal and keep the cabinet set to the right temperature. A broken or malfunctioning door can prevent your unit from maintaining specifications and cause strain on other components, so be sure to replace it promptly.
