An in-floor, flush poke-through wiring fitting may be installed in the floor of a structure to enable the activation of power, communication, and/or data services at the fitting location. The poke-through fitting internally supports four power receptacles and a plurality of communication/data jacks. The power receptacles may be connected in a single electrical circuit, or may be connected in dual electrical circuits. The poke-through fitting will support data connectors in either a flush mount position or a recessed mounting position. An excess cover includes separate sliding covers for each of the power receptacles and communication/data jacks.
