The Olympic retractable pull-down screen allows for natural ventilation of medium and large size openings. It’s the perfect choice for patio enclosures, gazebos, garage doors and other openings that are up to 10 feet tall and 16.5 feet wide. The motorized version comes with a hand held remote control allowing you to open and close the screen with the touch of a button. The remotes come in one channel or three channels and require a 120-volt connection. Also available is the manual version, activated using a child safe operating wand.
