PDQ developed a variety of electric hinges used in remote door monitoring and access control systems. The PDQ Hinges use convenient molex connectors to make installation quick and simple. These hinges provide a concealed and vandal resistant method for running wires from the frame to doors equipped with electric locks and exit devices. Electrified hinges allow a low voltage electric current to pass from the door frame leaf  to the door side leaf of a standard Architectural grade hinge.  Wiring is completely concealed when door is in closed position. This allows control of various electric items on the door (electric locks, access control devices, alarms, etc). They are available in different finishes and in either steel or stainless steel base material. PDQ Hinges are ball bearing hinges suitable for any door installation, especially desirable for doors with door closers installed.
