I installed a manual rollout retractable SunSetter home awning on our new home back in 2001. Here in Indiana I leave it in place from May through about November, since it has the screen room kit. This is a good accessory!
Works prefect for keeping my awning up so the door on my cargo trailer does not rip it
These are by far the best ones I have found. They stay on even in a fairly heavy wind. Anything heavier, I would retract the awning anyway. The straps were long enough for me. These are vastly superior to the all plastic 'T' shaped ones I had before. Highly recommed to anyone!
I'm at a long term site with my coach so my awning is out and anchored. But it was flapping constantly even in a light breeze. These de-flappers were the solution for me. They work in 15-25 mph winds and don't come loose. Any higher winds and they might pull loose. My only complaint is the connectors to the awning brace are way too short, so minus one star. I have an electric awning that folds out. So instead of the supplied hook-and-loop straps, I attached them with bungee cords and they work perfectly.
We've been in the high desert for a couple months now and the wind gets gusty. It's hot and we want our awning down for shade. Most days we end up putting the awning up in the afternoon (at the hottest part of the day) and suffering. These things have totally changed that!! Amazing what a huge difference they've made!
