Here are some pics...
The first is just a picture of the arch in the daytime.
The second is a photo of how I secured the vent clips. Basically I purchased some 1 inch metal rings, used Zip ties to attach the rings to the rebar running under EMT conduit. I then used a couple zip ties around the dryer vent and attached a ring clip to the dryer vent. Lastly, I clipped the ring clips to the 1" metal rings under the rebar. This let me secure the dryer vent, easily disconnect / store, and put everything up next year pretty fast. I might even leave the smart strings attached to the PVC - not sure though... As tightly as they are wrapped, I worry just flexing the PVC to a straight shape might take out a few nodes...
Lastly, I took a photo to show how much space is between the EMT and the dryer vent. You can't see it, but the entire SSC is stored above the zip tie / ring clip inside the dryer vent. I've got some super dry, super happy SSCs. Also keeps moisture out of the cat5 pigtails...
