I am running 6 inch round ridgid ducts in the ceiling of my basement. I have them sitting on temporary straps, but I want to remove those and install them right. I saw where you wrap a strap all the way around the pipe then attach it to the ceiling. I also saw where you put a telescoping bracket between the rafters under the ducts. What's the correct way to do this right please? .

I will also have a return run that will be vertical, so what's the correct way to do that too?
