Abstract: A convertible panel door-screen door closure for residential garage doors or commercial doors having a torsion spring mechanism for balancing the panel door and a roll-up mechanism for the screen door. The roll-up mechanism is mounted beneath the torsion spring mechanism on header plates. Roller tracks for the panel door are mounted in spaced relation to the standard door jams by brackets and the tracks for the screen are mounted between the jams and the panel tracks on the same brackets. The screen door and panel door have the same position with respect to the jams, immediately to the rear of the jams, when in their down positions, and hence only one door may be in the down or closed position at any time.
