An automatic pool cover closes over the water in under a minute, which is the difference between a cover you use daily and one you use twice a year. Four track systems cover most pools: manual, on-deck, recessed, and under-coping. Many existing pools can be retrofitted, while the under-coping system is built in during construction and is matched to our rectangle and contemporary L-shape kits. Owners often add solar covers for heat and keep a safety cover for winter.
