Safety Pool Covers come in Standard and Custom sizes Fine, lightweight mesh pool covers allow rain to seep through but screens out leaves and debris. Our durable, swimming pool safety covers have a break strength of 4,000 pounds. Safety pool covers are made of super-strong two-ply mesh that's held in place with brass anchors that recess flush with the deck when the cover is not in use. Swimming pool safety covers come complete with brass anchors, stainless-steel springs, installation tool and storage bag, and are backed by a 12-year warranty. These mesh pool covers are available in blue or green mesh, and in several standard sizes (see drop-down menu). All of our pool covers are made of polypropylene and meet all new regulations.
