The top door is for regular access, while the bottom is for easy access to frequently used items. A pass-through refrigerator can also be described as having a "glazed" or transparent door. Glass door pass-in refrigerators are made from tempered glass. They are straightforward to clean and maintain. The door has a magnetic seal and a handle. The shelves inside the door are adjustable. These refrigerators have LED lighting that shines on the food.
