A portable and collapsible screen unfolds and extends to provide a wall, divider or backstop which has many uses. The screen can be used as a backstop for ball games, a wind block, a privacy screen, or anywhere a small divider, screen or barricade is needed. Two base poles support a main pole where all the poles extend telescopically and a screen is attached to the far ends of the extended main poles. Anchoring means and floor base means are connected to the poles. Additional frame members and nets can be attached to extend the screen and form various shapes.
