We have several suggestions and some include some advanced banner finishing options. Upgrade to 18oz. Vinyl. It is more heavy-duty and stronger than our standard 13 oz. vinyl banner material. Make sure to use grommets every 2 feet and not just in the corners to put less tension on any 1 part of the banner. Add wind slits to allow for air from high winds to pass through with greater ease. Add reinforced corners. There is no option for selecting an upgraded 18oz. vinyl, reinforced corners, or wind slits online, but you can place your outdoor banner order and enter a note that you want these options in the "Got Comments" comments section (found on the file upload screen - see visual below), and one of our 4OVER4.COM reps will add that option to your order and advise you as to the additional cost. You can also contact our Support Team to assist in pricing and placing this order. Please make sure to provide as much information as possible for us to be able to get back to you quickly with a detailed response. Contact Support at Support@4over4.com
