Pleated screen system is operated by a cord tensioning system incorporated within the pleated insect mesh. This cord tensioner controls the tensioning of the screen making it smooth and easy to operate and resists mesh blow out in windy conditions. This modern stylish retractable insect screen is the perfect solution for protecting your family from annoying insects. Smooth to operate, slides to any position along the opening and is neatly stacked away when not in use.
