Sierra 800 Pull Down Retractable Screen for Large Openings

** Genius Retractable Screens provide insect protection and support fresh, natural ventilation in low-wind conditions. Unlike 4-sided rigid framed screens, Genius Retractable Screens move in and out of a protective cassette and the exposed surface area and edges of the fabric are flexible. Consequently, the wind speed that a retractable screen can withstand (e.g. before the edges of the screen fabric may push out of the guide rails), will depend on the width and height of the opening, the openness factor of the specific screen fabric and, other design factors of the model. Before retracting the screen check to see that the edges of the screen fabric are riding completely inside the vertical guide rails. If necessary, use your fingers or a soft smooth instrument to push the edges of the fabric inside the guide rails before retracting the screen.
