I got the screen from directly from springbar website. I couldnt find anything online about using it with a flexbow, but I set it up today and the screen fit well. The flexbow awning poles are about a half inch too long but I may get an adjustable tarp pole to use with it. The outdoor mat is really nice too. I tried to post a pic but I couldn't. Here is some links.
