Retractable screen doors are a great solution for out swinging french doors and doors where you do not want to constantly see a screen.
The are many different manufactures of retractable screens. We have tried them all.  The one we recommend is the clearview sceen door. It has standard features that the other companies do not offer (or charge more for).  The door is fully enclosed to protect the door from dirt and debris when not in use.  It also comes with a tensioner that keeps the door from slamming at no additional cost to you.
