The device is quickly deployable, thereby enabling users to enjoy the sun, breeze and the view, or to provide a level of privacy and protection therefrom as desired. The device can be installed without modification to the existing deck or balcony railing, and can be quickly set up or taken down as desired. The present invention may be used on residential and commercial decks and balconies, including either tubular spindle railings or on glass railing systems.
