A retractable screen is a home improvement product that is attached to the exterior face or to the interior frame of a doorway or window opening. The screening material itself is attached to a roller tube which spins on a vertical or horizontal axis within the assembly’s housing. The screen is also attached to a vertical or horizontal pull bar which rides on two rails and is used to stretch the screening material across the door or window opening. Once deployed, the pull bar is fixed in place by one or more magnets installed on the side opposite the housing. When not in use, the screen rolls up into its housing. The system can be installed on virtually any door or window, the system can be easily installed on French doors too.
