Im a little confused. I want to mount my projector to the ceiling. I am currently looking at the Chief RPA020. I was going to "flush" mount this projector as close to the ceiling as possible. If I don't use an adjustable extension column do I need another plate that mounts to the celing? Chief's website isnt 100% clear, at least not to me.
I do understand that if I want to drop the projector down a couple inches I need a Joist celing mount, extension arm and the mount for the projector.
