ABSTRACT:
After discussion of prior art electrical terminations for floor ducts in which a plurality of electrical cables are located, a pull-out receptacle for such floor ducts is disclosed which includes a sleeve configured to be received in an aperture extending between a floor surface and the interior of the floor duct, with the sleeve having a circumferential flange adapted to overlie those portions of the floor surface adjacent to the floor aperture. A recess is provided in a top surface of the sleeve, and an aperture extends from that recess through the sleeve. A closure member is provided which includes a core configured to be received within the sleeve aperture with a reciprocative, sliding fit, and an integral cap configured to be received in the recess. A first passageway is provided in the core, and a second passageway in the cap, the second passageway communicating with the first passageway for allowing electrical cables to be pulled therethrough. If desired, an electrical connector may be located in the first passageway so that telephone instruments or the like may be easily connected and disconnected when the closure member is withdrawn from the sleeve.
