ABSTRACT:
A cover for window frames that permit a user to selectively choose the frames where the covers will be mounted in an enclosure to protect the inside from the elements. An opening in the canvas that is mounted to the frame is selectively covered and uncovered to expose it. Velcro pads are used to keep the roll up cover sheet attached to the canvas when distended and in the rolled up position when the opening is exposed. String members and diverting roller assemblies are used to readily roll up and down the roll up sheet. A screen is super imposed over the opening to prevent insects from penetrating inside the enclosed structure.
