making a 90 degree turn

[phreak23]

I am starting a job that has a nasty 90 degree turn in the middle of a long run. This building is shaped like a squared "U" and many of the cables have to make a hard 90. Unfortunately, the cables are run on the inside of the turn. We are using hooks for support, but I need something to go on that corner to help with the pulling; I don't want the cable to rub on that corner. I looked at the "caddy" products, but don't see anything that will help. The customer opted out of using a tray for the cable.
We are pulling CAT6 Plenum, and probably 50 drops need to make that turn.

Any suggestions? I hope I gave enough of a description.

I got 3 of these on eBay several years ago and they make pulling cable a 1 man job in most cases:

If not then station a person in the corner to make the turn. They need to maintain 4-5' of slack while the cable is moving.

Cable Joes are the bomb! However, if you are pulling a follow string with the bundle, it will tend to get caught in the corners.

You could use some EMT 90's to make you corners. The distance of the 90 will depend on the size of the conduit you use. I usually put the press on poly bushings to protect the cables.

Attach a piece of uninstruct on both sides and use the clamps to hold the ends. Makes for a nice looking install.

Hell, there are no rules here - we're trying to accomplish something.

CableJoes all around. I always have the techs with atleast 2 each.

Other info: just using the conduit fill formulas as a supplement: 50 CAT6 at 0.23" dia needs a 2-1/2" EMT conduit that has a 2.731" conduit dia. The fill percentage is 35.5% and the conduit can handle up to 56 cables. The min inside bend radius of the conduit for a 90 degree bend is 27.31" with a developed length of build of 45.035".
