Every Aqua Brella™ Safety Pool Cover by Jersey Cover Corp is engineered and designed to be the safest and strongest cover possible. While some of the competitors use a single strap system on their covers, Aqua Brella™ Safety Covers are made with double strapping throughout the cover. The double strapping guarantees almost twice the break strength compared to the single strap. With our solid brass anchoring system and stainless steel springs, our goal is to make the safest cover possible. Our covers meet and exceed all ASTM standards, giving your family and your pool the Aqua Brella™ Blanket of Protection.
