The Cable Climber is designed to make it possible to have a retractable screen in spaces where the ceiling height is disqualifying for most screen systems. Stewart's dual motor system furnishes one motorized element to raise and lower the screen case and a second motor to deploy a wide range of Stewart’s optically immaculate 16K+ fabrics in sizes up to 16 feet 9 inches of image width. With Cable Climber your problem is solved.
