I have never done a vertical run of cat5 that was not pre installed in liquid 
tight.  So I cannot speculate on gripping just part of the jackets on the outer 
cables.  Cat5 jackets are pretty weak.  No idea how much tension they can take. 
 

But I might consider putting them in a 2’ section of thin walled tubing of some 
sort and  pouring in some kind of potting compound.  Then grip the potting 
compound.  

However 150 feet is not all that long.  Cannot imagine the weight being all 
that much.  Perhaps lash them to some kind of strength member and grip it.  
Maybe just spiral wrap the whole works with mule tape with vinyl tape or heat 
shrink if you are really wanting to do it up fancy at intervals. 

You can make a hand coil of mule tape that is longer than the run, pass the 
bundle through the core of the hand coil and then walk it down the bundle and 
it will deploy in a spiral fashion.  I have done this for telco cables and 
strand before.  Put the cable and strand through the coil of lashing wire and 
walk it along.  This is if you need to do an emergency repair of a span and no 
lasher.

Could you just use some of the heavy nylon pulltape that's 3/4" wide and just 
put a couple of halfhitch knots around the cables for support and tie it off to 
the hook?  Then you can just position the support where you need it once the 
cables are in.

  Has anyone used the “Chinese finger trap” style support grips for vertical 
runs of outdoor Cat5 cable in conduit?

   

  I need to support 8 – 10 cables in a 150 ft straight run of 2 inch conduit, 
there is a pull box with a support hook at the top of this run, then another 
~30 feet of conduit to a box at the top where the individual cables would go 
through glands and out to the radios.

   

  I did a test with a grip for 0.85 to 1.00 inch cable diameter, and a cable 
bundle that measured maybe 0.75 to 0.85 inches, and it’s very, very difficult 
to pass the bundle through the grip.  I can’t see sliding 50 feet of cable 
through it.  Even just a foot or two was a challenge.  Yet I’m reluctant to 
just use a larger grip, for fear it won’t grip properly.

   

  Is there a trick to using these things?
