Expansion Racks are functional and strong. They are made from durable anodized aluminum bars and are easy to store. They are ready to transport to churches, parties, trade shows, cemeteries, or anywhere a large display is needed. Combine the base rack with the available extension to add 30″ of height to your Rack, and create a truly impressive exhibit. Retractable hooks drop out when open, and disappear when stands are folded for easy storage.
