Well first summer is now behind us and it was time to close. Being in New England and wanting to keep the pool up vs disassembly, I thought I would post a few pictures of my current setup and its closing. I think I am just going to shrink wrap the entire pool seeing as I have more of that...
I use 550 cord and what is called a barrel hitch.
The top of my barrels have weep holes that I attach another 2 550 cord lengths to, and place it using 3 tie downs. That way I can center it where I want it in the middle of the pool, and the cats can't move it.
I will take pictures when I do it this year for you, but, as I live in the "Deep" south, it may be a bit late in the season for you.
I have a 21" AGP. I did the same thing. However, I drained my pool below the filter lines. Since the water line is lower, the barrel does not hold the cover up very high in the middle. Do you drain your pool?
In reading this thread, I was wondering why anyone would use something as large as a 55 gallon drum as support for a cover. That explains it. Since I don’t drain my pool, I’m able to get away with a couple of pieces of styrofoam, which are more easily managed.
