The Integrated Door system offers a universal lock case and a heavy-duty top latching mechanism designed to accept various operators such as an inset exit device (UL 305 listed), dual or single levers, or a smaller pushpad for non-exit-device applications. All configurations are tested and listed to UL 10C. A bottom bolt is available if extra security is desired. The locking mechanism offers most functions found in exit devices and mortise locks and a range of electrical options. Installers can fine tune the door to the opening with a screwdriver.
