Abstract
Abstract This invention relates to an improved installation panel duct adapted to contain electric wires for power current as well as for low voltage communication, the panel duct consisting of an elongated base member and an elongated cover member adapted to be secured to said base member by means of a snap-fit connection, the arrangement of a coupling device for connecting an insulating housing for an electric device such as a switch or an outlet socket to the panel duct in alignment with an opening in the cover member, said coupling device comprising a primary and a secondary coupling member, said primary coupling member having means for snap-fit connection with the base member and means for attachment to said insulating housing, the secondary coupling member consisting of a cover plate for covering said opening in the elongated cover member and being provided with means for detachable connection with the primary coupling member and means for snap-fit connection with the base member.
