  • Office panel with lay-in communication cable capability
    Patent number: 5214890
    Abstract: An office panelling system is disclosed which readily accommodates the initial or retrofit of communication cables and the like cables which generally do not require an electrical conduit. The individual panels of the system have a metal framework to which decorative covers are secured. The framework and covers have been adapted to define a passageway along the panel which is accessible by removing of the covers. With this arrangement, communication cables may be installed without stringing of the cables through ports in the framework.
