Screen Tight. Using a system of 1-by-2-inch self-mating channels and molded clips, the FastTrack Porch Screen System allows for easy installation and project creativity. The channels hide the clip fasteners for a clean look, while allowing for different configurations, which can include a railing system, vertical mill posts, and horizontal rails. The system lets users screen from the interior or exterior of the porch using a flat spline. 800.768.7325. www.screentight.com.
