Arctic Armor Winter Covers, 18 ft. Round Pool Size, 22 ft. Cover Size (WC904-4)

Constructed of our strongest and most tear resistant material, this cover features rugged U.V. stabilized woven polyethylene that protects it from sun, snow, wind and ice. It features a black underside to retard algae growth and heat sealed seams ensure a crystal clear pool next spring. This cover has a 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. This 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 limited warranty (3 years full rated).
