Abstract
A lock system for the inactive door of a two door swinging combination is provided which prevents the active door from being latched or completely closed without locking the inactive door in place against the door frame and/or floor. Further, with the active door closed, the latch of the active door prevents movement of the slider of the inactive door lock mechanism and thereby prevents any unlocking of the inactive door until the latch of the active door has been removed and the active door opened.
