The LG AAP73871601 Refrigerator Door Shelf Bin Assembly. This replacement shelf bin is designed for select refrigerator models from LG Electronics and provides a designated space for bottles, jars, and frequently used items. It works by fitting into the molded mounting supports on the interior door panel, where it locks into place to hold items steady during everyday opening and closing. Made from durable, food-safe plastic, it helps prevent tipping and keeps contents organized and easy to access. Replacing a cracked or worn bin restores proper storage capacity and supports the continued functionality of your refrigerator.
