This Avantco 17811290 black glass door is a direct replacement for the one that came with your Avantco black merchandiser freezer. Use it to replace a worn or broken part to ensure your unit is operating efficiently. 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. It features a right-hinged design. It's compatible with Avantco GDC-9F-HC black merchandiser freezers.
