A window or door limiting device is described having a striker assembly mounted on a window sash or door panel and a corresponding limiting assembly mounted on an adjacent window sash or door panel. The limiting assembly selectively engages the striker assembly with a rotary element to restrict movement of at least one of the first or second window sash or door panel relative to the other of the first or second window sash or door panel. The rotary element is rotatable to selectively engage or disengage the striker assembly to correspondingly restrict movement of one or more of the window sashes or door panels.
