  • Data transmission pedestal with internal service line passage
    Patent number: 6462269
    Abstract: A data transmission pedestal housing having a service line passage is disclosed. The passage is structured to have a gap allowing service lines to pass into and out of the service line passage. An extruded gap closure element is provided for sliding engagement with walls of the passage so as to close and open the gap. When the gap is opened, a service line may pass out of the passage through the gap thereby allowing the pedestal housing to be removed and replaced without disconnecting the service lines from terminal blocks that connect to a cable.
