ABSTRACT:
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 two series of knock-out discs for mounting both left-handed and right-handed lighting fixture receptacles. 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.
