The majority of metal A-Frame models are made with snap-edge frames and slide-in panels, permitting frequent updating of messages, menus, and lists of services. They are a top pick among restaurants, retail stores, and automotive repair shops with high-frequency message updates. Companies are also able to insert a chalkboard or a magnetic surface for a daily updated reusable board with special and promo information.
