  • Patent number: 7424990
    Abstract: A ducting system and method for managing fiber optic, or other sorts of cabling. The duct has perforated circular punchouts in its sides. To drop cables to equipment below, the user simply punches out one of the circular perforated sections in the duct. This will leave a hole, which is sized to receive a downspout. Instead of punchouts, holes for the downspout could simply be drilled in the initial product. Regardless, the downspout is dropped to its full extent through and out of the duct through the hole, and is then retained by a grommet which bears against the interior of the duct. Once the downspout is secured in the hole, the selected cables are dropped from the duct through the hole, down the downspout, and into standard ribbed flex tubing, which may be force fit onto the downspout.
