  • Raceway system with separated wireways for power and data communication conductors
    Patent number: 6323421
    Abstract: Raceway base and cover components define top and bottom wireway channels, and provide a third channel therebetween for housing various outlet devices that need not be placed in the wireway channels. The dividers defining these channels are molded as part of the base, and define hinge lines so that shelf defining doors can be opened for ease of wiring the raceway, and closed for isolating the cabling contained therein. Device brackets are snapped into the third channel and these device brackets are designed to receive the outlet devices as a result of a snap-in feature disclosed in a prior art U.S. Pat. No. 5,594,205.
