This rectangular inground pool safety cover is designed for 18 ft. x 36 ft. pools with a 4 ft. x 8 ft. side step, giving 2 ft. of overlap to seal edges and reduce fall risk. The high-strength polypropylene mesh stays flexible from -22°F to 140°F, resists UV aging, and maintains dependable protection through several winters. The fine 0.3 mm weave lets rainwater pass through while catching leaves, twigs, and pinecones, so owners can spend less time draining or deep cleaning. This safety cover meets ASTM F1346 and supports up to 400 lb, making it a practical safety barrier for homes, hotels, and other properties with children or pets. It includes brass anchors, stainless steel springs, and installation tools, so one person can complete the three-step measuring, drilling, and tensioning process on concrete or stone decks. During winter, the dust- and stain-resistant surface keeps pool water cleaner and reduces spring opening work; simply remove the cover and rinse off debris before storing. Check anchors and springs periodically and keep the cover in a dry, shaded area when not in use. Color: Green.
