ABOVE-GROUND ARCTIC ARMOR— GOLD 15-YEAR WARRANTY This winter cover is built to last! Constructed of our strongest and most tear resistant material. This cover features rugged stabilized woven polyethylene that protects it from sun snow wind and ice. It features a black underside to retard growth and heat sealed seams to ensure a crystal clear pool next spring. The cover has a big 4 foot overlap that means it will fit pools with wider top rails and will not stretch and rip like smaller 3 foot overlap covers. Our Gold grade cover is held secure by a heavy duty vinyl coated cable and tightener that is anchored to the cover by rip proof metal grommets. This rugged cover is built to last so it is backed by a 15 year warranty (3 years full rated). Invest in quality this fall with Arctic Armor Gold.
