Product details:
Protect your above ground swimming pool with the Pool Mate Guardian solid winter pool cover. The polyethylene material, which does not allow water to pass through, is constructed with a 10x10 scrim (threads per square inch). Covers with a higher scrim will have a better overall quality, strength, and durability. The material weighs 2.91 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. 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 approximately every four or five 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.
