These are heavy duty and a quality product. We needed something to block the view of our trash can and lawn tractor, this worked great. The only problem is wind. It was fine with a gentle breeze, but when it turned to a gust they both blew over with a crash. One got tweeted a little but not bad. My husband came up with a solutions by putting a 8' piece of lumber across the feet of both screens on one side plus putting 5 cement blocks on this. He also noticed the vibration from the wind made some of the bolts come lose so he added washers. This all did the trick, I'm so glad because I would have hated to return them, they look so good.
