Ummm, they are referred to mostly as "tailgator" flag poles.

Barry got his from a travel trailer dealer. Not sure where Paul got his.

I got my alum. from Ebay. I also use it at home for the great American Flag!

If you want to attach 2 flags, make sure the pole is designed for it.

Just a note, contact one of your state elected officials and they can provide a state flag free of charge!
