If you hang figure 8 type of stuff from poles, twists are imperative. They keep it from oscillating up and down in the wind. If you don’t twist it will shake itself to death.

Looks a lot like this stuff: http://www.duraline.com/conduit/figure-8 It's meant for aerial installation. I used it from the roof of the elevator down to a shelter. I pulled regular power and fiber cables into it. The stuff is pretty heavy - I hauled it up to the roof with a capstan winch, and ended up tensioning it with the winch as well. Check the local utility supply houses to see if they have a partial reel sitting around. Use a 'Strand Vise" to attach the messenger wire to anchor the ends. The EHS cable is a bitch to cut - a grinder works great. One thing I learned after putting it up - leave a few twists around the messenger strand. You want the tube wrapped around the messenger a couple of times so that the tube part is not hanging below the messenger the whole way. I tried to make it nice and neet and took all the twist out of it when I hung it. Turns out that was wrong. It's not showing any signs of coming apart fortunately.

Is there some kind of figure 8 cable that has an integral steel cable that would be better? I’m not talking about FTTH on utility poles, this is for a grain elevator where burying the cable is not practical. Basically going from a building on one side of the bins to a building on the other side, where we can pick existing buried fiber to yet another building.

SE 12D or similar. Everyone else wants to sell me 3300'. Anyone out there willing to part with a couple hundred feet? I'll get you exact lengths as soon as I find someone willing to sell me a bit.
