ABSTRACT:
A raceway structure for association with a wall panel so as to enclose and confine power and communication cables which extend longitudinally along the wall panel and longitudinally throughout several series-connected such panels. The raceway structure utilizes a pair of side covers which removably attach to the wall panel and cooperate to define a raceway for enclosing therein electrical terminals and communication cables. The raceway structure has access openings for providing convenient access to the electrical terminals, such as by permitting an electrical receptacle, power feed, or communication cable to be positioned therein or passed therethrough. The side cover has a closure integrally hinged thereto for closing the access opening when use of same is not desired, with the closure being swingable into an open position within the raceway while remaining integrally attached to the cover when use of the opening is desired, whereby different openings can be selectively utilized when desired and then closed again when use of the opening is not desired.
