Pulling Tension on Cat-5

I have heard 25 lbs., and I think manufacturers list it in the cut sheet of the cable, which is typically not included in the box.

Yes, it is found in the manufacturers spec sheet. Most manufacturers of Cat.5 will state 25 lbs. max pulling tension but I used Cat.5 recently that I could swear max. pulling tension was 15 lbs. but I dont remember the manufacturer.

If it's a bundle, the pulling tension is 80% of the sum of the individual cables. Hence, a bundle of 4 cables would have a pulling tension of 80lbs, and so on.

Take a look in ANSI/TIA/EIA 568 B ....it is 25 lbs.
And it is my understanding that the permitted pulling force in that document does not go up as you add cables. It is 25 pounds max for one cable and does not go up as you add cables to the pull. That is the document does not permit a pulling force of 250 pounds for a bundle of 10 cables.
