This listing is for a Metal Wing Extension For an A&A Vending Stand (BLACK). It is used but in good condition. These were designed for the A&A Vending Stands as a way to add one extra machine to your stand without having to increase the size of your stand. For example, you could add a 2 column sticker machine or a changer machine. You only have to remove to screws and then reattach. Super simple! The holes are pre drilled and you use the same brackets as the stand. I’ve included a photo to show how it works.
