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.

Claims (29)

1. A method of maintaining a plurality of cables disposed in a duct, comprising

providing a duct comprising a longitudinal floor, a first longitudinally extending side, and a second longitudinally extending side opposing said first side, wherein each of said longitudinal floor and said longitudinally extending sides have an inside surface;

creating an aperture in one of said first longitudinally extending side, said second longitudinally extending side, or floor defining a first aperture for the purpose of routing at least one of said plurality of cables from said duct;

providing a downspout having first and second ends;

inserting said first end of said downspout through said first aperture, causing the first end to depend from said duct, wherein inserting comprises:

disposing a grommet on said second end of said downspout;

catching said grommet on said inside surface of one of said longitudinal floor or said longitudinally extending sides; and

retaining said second end of said downspout on said duct with said grommet; and

running said at least one cable through said downspout.

2. The method of claim 1 , comprising:

selecting said first side as the location for the first aperture.

3. The method of claim 2 , comprising:

creating a second aperture in said second side for routing at least one other cable of said plurality away from the duct.

4. The method of claim 2 , comprising:

creating a second aperture in said first side for routing at least one other cable away from said duct.

5. The method of claim 1 , comprising:

using said downspout to guide said at least one cable.

6. The method of claim 1 , comprising:

coupling said first end of said downspout via a force fit into an inner surface of a standard piece of ribbed split tubing.

7. The method of claim 1 , wherein said creating step further comprises:

making a portion of said duct removable by circumscribing it within a weakened outline; and

knocking out said portion to create said first aperture.

8. The method of claim 7 , wherein said circumscribing is done using perforations.

9. The method of claim 8 , wherein the perforations are made such that knocking out said portion to create said first aperture is performed upon a user manually pushing on said portion.

10. The method of claim 1 , comprising:

providing each of said longitudinally extending sides with a plurality of longitudinally extending reinforcing ribs that promote structural integrity thereto.

11. The method of claim 1 , comprising:

providing said downspout that is substantially cylindrical being formed with a curvature, wherein said curvature being defined by a radius; and

retaining said second end of said downspout on one of said longitudinally extending sides with said grommet such that said curvature directs said at least one cable downward in relation to said duct.
