6. The cable roller of claim 1 , wherein a plurality of rollers are mounted on said support assembly.

7. A cable roller for use in positioning a cable comprising:

a mounting channel having opposite ends and a length defined between said opposite ends;

a support assembly attached to said mounting channel, said support assembly includes a support channel connected to said mounting channel, first and second legs extending downwardly from said support channel, said first leg being hingedly attached to said support channel, and a cross-bar extending between said legs upon which said at least one roller is mounted, said cross-bar being detachable from said second leg; and

at least one roller attached to said support assembly for allowing the cable to roll over the at least one roller.

8. The cable roller of claim 7 , further including a connector assembly for connecting the support assembly and the mounting channel together, said connector assembly including a nut and a fastener, said nut being mounted within said mounting channel and attached to said support assembly, said fastener attached to said nut for capturing said support assembly between said fastener and said mounting channel.

9. The cable roller of claim 7 , wherein each said leg of said support assembly is hingedly attached to said support channel, and said cross-bar is detachable from each said leg.

10. The cable roller of claim 7 , wherein said mounting channel is mounted on a ceiling of a building.

11. The cable roller of claim 7 , wherein said mounting channel is mounted on a cable tray.

12. An assembly for use in positioning a cable comprising:

a cable tray having a base upon which the cable can be laid and tray hangers extending from the base; and

a cable roller comprising a mounting channel having opposite ends and a length defined between said opposite ends, said mounting channel being suspended above said base of said cable tray, a support assembly moveably attached to said mounting channel, said support assembly being moveable along at least a portion of said length of said mounting channel, said support channel inducting first and second legs extending downwardly from said support channel, each said leg being hingedly attached to said support channel, and a cross-bar extending between said legs upon which said at least one roller is mounted, said cross-bar being detachable from said first leg and from said second leg, and at least one roller attached to said support assembly for allowing the cable to roll over the at least one roller.

13. The assembly of claim 12 , wherein said mounting channel is attached to said tray hangers and said mounting channel has a pair of elongated slots at each end thereof into which said tray hangers are mounted.

14. The assembly of claim 13 , further including a coupler assembly for connecting the mounting channel and the tray hangers together, said coupler assembly including a pair of 1/4 fasteners mounted on said mounting channel above said respective slot.

15. The assembly of claim 12 , further including a connector assembly for connecting the support assembly and the mounting channel together, said connector assembly including a nut and a fastener, said nut being mounted within said mounting channel and attached to said support assembly, said fastener attached to said nut for capturing said support assembly between said fastener and said mounting channel.

16. The assembly of claim 12 , wherein said mounting channel is attached to said tray hangers and further including a coupler assembly for connecting the mounting channel and the tray hangers together, said coupler assembly including a 1/4 fastener.

17. The assembly of claim 12 , wherein said mounting channel is attached to said tray hangers and further including a coupler assembly for connecting the mounting channel and the tray hangers together, said coupler assembly including one of a nut and a clamp attached to each said tray hanger, said mounting channel sitting on top of said coupler assembly.
