Have YOU come to right place!!
#1 - Now that you have dry fitted your brackets, bring em on back down, prime and paint, then reinstall.
#2. Follow the diagrams and specs for the do it yourself poles found in the awning thread. OR...
#3. Do the quick and dirty like some of us and use expandable painter poles
They are light weight.. but not as light as OC's.. cost a fortune more, but they are pretty much ready to paint and install out of the box with just a few modifications such as adding additional height adjustments holes. You'll probably want to add some kind of "foot"
(tons of other examples that others use in the thread) to your poles.. and you will want to make sure you have a decent spiral type tie down kit (which is the whole intention of your O.C. brackets).
#4. If you plan to travel with your OC poles in the installed/stored position, you'll need to pick up some D clips. At least for the upper and storage brackets. I use an additional set for the "feet" on mine.
If you DO go another route than the PVC's make sure you make drain holes at the bottom as needed to allow for rain water to exit your poles. There is nothing like retracting your O.C. poles and getting an up-spray of water from the filled lower leg.
Ask Epy. I don't know how many times he has retracted his and gotten a "spray wash", but we are all waiting on baited breath to see if he has learned his lesson yet.
Disclaimer: I don't even know for sure if Epy even has O.C. poles, but had to throw in a "rip". It's been far too long.
