This Avantco 17831016 bottom solid door is a direct replacement for the one that came with Avantco DDLC-71-S refrigerated deli cases. It's a vital part of your deli case'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.
