The Bestway 58039 round pool cover uses a drawstring closure type. It is specifically designed to be secured to the pool using included ropes or drawstring ropes, which ensure a snug fit and prevent the cover from blowing away in windy conditions.
Compatibility: Designed for 18-foot (5.49 m) round above-ground pools, specifically the Bestway Steel Pro MAX and Power Steel series.
Material: Constructed from durable, UV-resistant PVC (Polyvinyl Chloride) material to withstand weather conditions and protect against sun damage.
Drainage System: Features integrated drain holes that prevent rainwater or excess water from accumulating on top of the cover, which helps avoid damage and safety hazards.
Maintenance: Helps keep debris, leaves, and insects out of the water while also reducing water evaporation and algae growth.
