The present invention is an instant screen door. It has a closure on a roller or rod with attached brackets that position the closure at a minimal distance from the wall, outside the frame, and at the top or above the frame, so that the closure covers the frame completely and closely, thus making it useful for barring insects, light or visibility (for privacy) since the closure may be opaque, transparent, paneled, solid or latticed. My instant screen door can be easily and quickly mounted without marring the frame and readily removed for storage or for transfer. A user simply compresses the brackets, inserts the present invention in the frame, and releases the compression. Then, an expansive pressure assembly located inside the roller or rod forces the attached non-marring brackets into static frictional engagement with the stiles of the frame. The present invention can be mounted on frames of different types and widths because its rod or roller can be telescopic and its brackets provide three dimensional adjustability: the distance between the brackets can be increased, the height of the roller or rod can be increased, and the position at which the brackets contact the stiles can be adjusted to various depths within the frame. Two practical uses would be as an inexpensive screen door to the outside or as an opaque closure for an interior archway. It would be particularly useful for apartment dwellers who are prohibited from defacing their building.
