The ODL Retractable Screen for Sliders is 36"W x 78"H and is designed for sliders of wood, vinyl or steel. It's there when you need it, out of sight when you don't. It is a practical and attractive solution to your need for a screen door. When fully deployed, it has all the advantages of a traditional screen, but when retracted, it blends with the door frame to provide a clear, unobstructed view. Comes with a five year warranty.
