I bought a feherGuard solar cover reel for my above ground 21 ft round pool. Problem is the pool is enclosed with a deck so there is no way to swing the thing out of the way. Instructions only show this thing mounted in the middle of the pool. Looks like the cover is in half and then is pulled out from both sides. Befroe I take this thing back I am wondering if there are any other options. Can the thing be mounted on the deck at the end of the pool? If so, would the cover even work, and am not clear on how you would mount the straps or where on the cover. Any help would be appreciated.
