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.

Then you can just position the support where you need it once the cables are in.

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? https://www.graybar.com/store/en/gb/0850-to-1-inch-kellems-galvanized-steel-single-eye-bus-drop-support-grip-88147585 -------------------------------------------------------------------------------- -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com
