ABSTRACT:
An apparatus for providing an electrical connection from a power source, through a stationary door frame, into a door to connect to door-mounted electrically-operated hardware, includes an electrical junction box installed in a mortise cavity in the door frame adjacent to a similar electrical junction box installed in a mortise cavity in an edge of the door. The junction boxes are adjacent each other when the door is in a closed position; and a housing is installed in each junction box, each housing having a longitudinal slot in a face plate thereof of a length substantially equal to the length of the junction box. A cover plate is longitudinally slidably engaged in grooved fingers on a rear surface of the face plate, the cover plate having a substantially circular hole. A hollow tube, having an elbow swivelably mounted on each end, has one elbow swivelably engaged in the substantially circular hole of the cover plate of the housing mounted in the door frame and the other elbow swivelably engaged in the substantially circular cover plate of the housing mounted in the door. A conductor cable connected to a power source, in the junction box mounted in the door frame, extends through the elbows and the hollow tube into the junction box mounted in the door, and connects to leads to door hardware mounted in or on the door.
