Cable management fitting

1. A cable tray assembly comprising:

two rails forming sides of the cable tray assembly;

rungs connected to and extending between the two rails, each rung including a body having upper and lower ends, a lower flange at the lower end of the body, and an upper flange at the upper end of the body; and

a cable management attachment fitting secured to one of the rungs and including

a rung attachment portion attached to one of the rungs of the cable tray assembly without the use of an additional fastener, and

a cable management attachment portion extending from the rung attachment portion and configured to provide a structure to which a cable management device can be secured, wherein the cable management attachment portion includes an arm extending upward from the rung attachment portion, and a cable attachment flange extending laterally outward from an upper end of the arm adjacent the upper flange of the corresponding rung,

wherein the cable attachment flange extends in a direction away from the upper flange of the corresponding rung.

2. The cable tray assembly set forth in claim 1 , wherein the rung attachment portion is attached to the lower flange of the rung by one of a snap-fit and an interference fit.

3. The cable tray assembly set forth in claim 2 , wherein the lower flange of the rung includes first and second portions on opposite sides of the body of the rung, wherein the rung attachment portion is attached to the first portion of the lower flange, wherein the arm extends upward from the base adjacent the second portion of the lower flange.

4. The cable tray assembly set forth in claim 3 , wherein the rung attachment portion comprises a hook configured to hook onto a terminal edge margin of the first portion of the lower flange.

5. A method of attaching a cable management attachment fitting to a ladder-type cable tray comprising:

providing a cable management fitting including a rung attachment portion configured to attach to a lower flange of a rung of the ladder-type cable tray without the use of an additional fastener, and a cable management attachment portion extending upward from the rung attachment portion and configured to provide a structure to which a cable management device can be secured, wherein the cable management attachment portion includes an arm extending upward from the rung attachment portion, and a cable attachment flange extending laterally outward from an upper end of the arm, wherein the cable attachment flange and the rung attachment portion extend outward from the arm in opposite directions; and

attaching the rung attachment portion to the lower flange of the rung of the ladder-type cable tray without the use of an additional fastener, such that the cable management attachment portion is adjacent an upper end of the rung and the cable attachment flange extends in a direction away from the upper flange of the corresponding rung.

6. The method of attaching a cable management attachment fitting to a ladder-type cable tray set forth in claim 5 , further comprising:

securing at least one cable to the cable attachment flange using a cable tie.

7. A cable tray assembly comprising:

two rails forming sides of the cable tray assembly;

rungs connected to and extending between the two rails, each rung including a body having upper and lower ends, a lower flange at the lower end of the body having first and second portions on opposite sides of the body, and an upper flange at the upper end of the body; and

a cable management attachment fitting secured to one of the rungs, the cable management attachment fitting including:

a base in generally opposing, face-to-face relationship with a lower surface of the lower flange, the base having a first end and a second end,

a hook at the first end of the base, the hook defining a channel in which the first portion the lower flange of said one of the rungs is received,

an arm portion extending upward from the second end of the base toward the upper flange of said one of the rungs, and

a cable attachment flange extending laterally outward from an upper end of the arm portion, wherein the cable attachment flange extends in a direction away from the upper flange of the said one of the rungs.

8. The cable tray assembly set forth in claim 7 , wherein a lip extending downward is disposed at a terminal end of the cable attachment flange.

9. The cable tray assembly set forth in claim 7 , wherein the base and the cable attachment flange are generally planar.

10. The cable tray assembly set forth in claim 7 , wherein the base, the arm portion, and the cable attachment flange are formed from metal.

11. The cable tray assembly set forth in claim 7 , wherein the cable attachment flange and the base extend laterally outward from the arm portion in opposite directions.
