Hello all. I am looking to get a manual track system pool cover. My pool measure 14x24 and I don't mind having rails on either sides with a box at the end of the pool to keep the rolled up cover. I also don't manually pooling it and/or cranking it to open or close it. Has anyone installed one of these? I pretty handy and can even build it myself if anyone has any suggestions on parts, etc.. Or maybe I can order one online? TIA
