A retractable material enclosure system that can be custom fit to provide a secondary barrier within an opening that is unobtrusive when not in use. The retractable material enclosure system may be used with different types of materials that are capable of being rolled about and retained on a cylinder or other drum type member when they are not extracted and in use. The retractable material enclosure system is particularly useful for providing a custom fit retractable screen door that fits within single or double door opening.
