ABSTRACT OF THE DISCLOSURE An electrical raceway for installation in an illuminated sign box of the type having a translucent sign panel is in the form of an elongated and hollow structure which provides reinforcement for such a sign box and a housing for electrical conductors. Such raceway has a cover having two series of knock-out discs for mounting both left-handed and right-handed lighting fixture receptacles and has a channel having bottom and side walls, with reinforcement ribs in the side walls which cooperate with suitable complimentary ribs in the side flanges of the cover to provide strength, as well as a snap-on fastening for the cover. When such raceways are installed in a sign box, the lighting fixture receptacles can be mounted so that the lighting tubes extend between two such raceways completely across one of the series of knock-out discs in each such raceway thereby improving the overall illumination of the translucent sign panel, and reducing the patches of varied light intensity.
