Pool Mate Heavy-Duty 8-Year Blue Round Above Ground Winter Swimming Pool COVER, Size: 30 ft Pool DUR83_D5749

Product details:

Protect your above ground swimming pool with the Robelle Super solid winter pool cover. The polyethylene material, which does not allow water to pass through, is constructed with a 8x8 scrim (threads per square inch). Covers with a higher scrim will have a better overall quality, strength, and durability. The material weighs 2.36 ounces per square yard which is important because heavier covers will be affected less by extreme elements. The topside of this cover has been treated to inhibit UV rays and the bottom of the cover is black to help prevent algae growth. This cover has an additional four foot overlap to ensure complete coverage of pools with top rails of up to nine inches. Two aluminum grommets, four inches apart, are placed every four feet around the perimeter of the cover and two lines of double chain stitching secure the hem. The included plastic coated cable and locking ratchet tightens the cover securely around the pool.
