Abstract
A safety device for screen and storm secondary doors in which a movable rod is horizontally mounted on the door jamb proximate to the latch receiving mechanism. The closure of the inner or primary door urges the rod into position so as to disable the latching mechanism of the screen door. The opening of the primary door enables the rod to be withdrawn thereby permitting the secondary door to be opened.
