A slip-ring device includes a cable, a stop-sleeve, a cable coupler, and a slip-ring. Preferably, the stop-sleeve is coupled to the cable. The cable coupler includes a hollow portion that can pass the cable and a surface having an opening sized to restrict an axial movement of the stop-sleeve. A slip-ring is coupled to the outer circumference of the hollow portion. A method of mounting a fixture to an enclosure includes inserting a portion of the cable through the cable coupler; coupling the cable coupler to the enclosure; positioning a canopy over the stem of the cable coupler; and fastening the canopy to the enclosure by threading the slip-ring to the cable coupler.
