Banner Ups products allow you to create super-strong banners instantly at a fraction of the time and cost of grommeting. Banner Ups, PowerTabs, and EdgeTabs are stronger than grommets because they spread the stress of high winds over a much larger area. Banners made with Banner Ups withstood sustained wind tunnel tests of 50-70 miles per hour. Banner Ups aren't just for banners. Use Banner Ups anytime you need a fastener for plastic film, posters, or lightweight board.
