The thing I ordered is to take the place of an AG cover reel because there is no good way to mount a reel to an AG pool and the ones they sell for AG pools are flimsy. I bought something called a Solar Roller Cover stick. I haven't tried it yet because in the past month or so we have been replacing the pool (old one was 24ft, new one is 27ft), building a new deck and reinstalling the solar panels and burying the pipes. However, that was all finished this week and I plan to put the solar cover on in the next day or so and try out the new device. I'll be reporting on it shortly. If it works the way the online demo shows, it is gonna be great!

Big Dave mentioned me cutting my previous solar cover into fourths. You can read about this and see pics in this thread. (That was better than having it as one huge piece of vinyl, but I'm hoping that my new thing is even better.)
