These Retractable Screens are top of the line luxury with built in, full enclosed, pulley systems designed to give two finger control. These screens may stop anywhere within the travel path and are not operated by a full tension spring. Most retractable screens of this size have large "full tension springs" that are under heavy loads while the screen is deployed. These springs will often pull out of the user's hands as they try to open the screen to pass through. The retractable screen you see in this photo will go up to 10' tall x 24' wide, with a completely clear opening. The screens are also available in insect screen, solar screen, privacy screen, and combination screens. They are completely incased and have billet aluminum frames. This Retractable Screen is the perfect solution to the Custom Builder or Architect needing a large span screen solution. These are also great for noise abatement within open floor plan homes and structures. Knock down echoes, close off TV or office spaces, or create sections within a large space for a more intimate setting in seconds.
