At the shop they had the fan ziptied to one of the vertical poles to the tent and on another tent they had the fan just dropped right on top of the tent and it vented straight out the hole in the top. Im thinking that I will try the ziptie method and see how that works out.
Hammy, I cant even tell you how happy I am with these hangers. They had about 20 lights hanging up at the shop and half were hung with these hangers so I got to see how they worked and was very impressed. I have been using chains and S hooks for years now and I am so happy to throw all that crap away. On these new hangers you just set the desired tension, depending on the weight of the light, and then you can pull the light up or down and it will lock itself in position.
