Yah, I now realize I didn't get specific as to what I was asking about. I made it look like I was just asking about a net on a pole, when I was really asking about the net that covers the entire pool and ties down with a cable around the side. Well, I knew what I was talking about, you mean you couldn't read my mind? D'OH!!
So measurement is full diameter of net, not what pool size it would go on.
