A LOOP-LOC Safety swimming pool cover is different ! It's made of a fine, strong mesh that allows rainwater to pass right through. Dirt and debris blow away, so the cover always stays dry and neat looking. It's designed to hold to the exact shape of your pool with stainless steel spring and brass anchors that fit flush with your deck when the cover is not in use. Obviously, a dry, taut swimming pool cover that never needs pumping out is a lot safer for children and pets to be around. And LOOP-LOC swimming pool covers are so durable and so well made that they come with a 15 Year Prorated Warranty ! That's why it's smart to insist on a LOOP-LOC cover for your pool this year!
