There's no screen door at the entrance to my upper flat. I've had issues with bugs flying inside for years. This hanging screen is just what I needed. It's cut to my size (I wish I'd added another 1.5 inches to the width). The screen has soft velcro on all sides. I put up the hook side (the rough side) of velcro all around my doorway.The Velcro helps hold the screen closed - no little gaps for bugs to fly in through. It's nice to have this in place and to be able to leave my door open all of the time. I don't have to worry about lights inside my house attracting bugs - the screen locks them out. I'm very happy.
