The American Society for Testing and Materials [ASTM] F1346-91 (1996) standard requires that a cover hold a minimum of 485 pounds per five square feet to qualify as a safety pool cover. These safety pool covers usually come in two varieties or style:  Mesh & Solid.   Both types of safety covers are anchored to a deck with straps that pull the cover taut over the pool, the straps usually attach to stainless steel springs and are anchored to recessed brackets in a deck surface. When the cover is removed, deck brackets that are not already flush with the deck can be screwed down to prevent tripping or toe-stubbing. Because the straps need to be anchored down, mesh covers generally require at least two to three feet of decking all around the pool. There are a variety of deck anchors for all types of decking material including, but not limited to, concrete, brick, asphalt, earth and wood.
