Aibiley 21FT Above Ground Pool Winter Cover (Actual 25FT) — Heavy-Duty Waterproof, UV-Resistant with Winch Kit

Aibiley's 21FT round winter pool cover (actual 25FT) is a heavy-duty, waterproof and UV-resistant cover engineered to protect above-ground pools through extreme weather and winter months.

Keep leaves, snow, and debris out of your above-ground pool while extending the life of your pool liner and equipment. This Aibiley cover is built with high-density polyethylene fabric, reinforced nylon webbing, heavy aluminum grommets and an upgraded winch-and-cable kit to deliver a snug, weatherproof fit for pools up to 21 feet in diameter. The larger 25-foot actual diameter provides a 4-foot overlap so the cover fits securely over inflatable, frame, and steel-wall above-ground pools.

How durable is the material against tears and extreme temperatures?

The cover uses tightly woven PE with an 18x18 scrim count and a 190 gsm (6.7 oz/d²) fabric density, producing a robust 0.56 mm thickness that resists punctures and wear. Edges feature 2-inch nylon webbing to reduce ripping where strain concentrates, and heavy-duty aluminum grommets prevent deformation during tensioning.

• Tight 18x18 scrim count polyethylene fabric (190 gsm)
• 0.56 mm material thickness for tear resistance
• 2-inch reinforced nylon webbing along perimeter
• Heavy-duty aluminum grommets to withstand pulling forces

Will this cover survive winter snow, freezing cold, and hot summer weather?

The Aibiley cover is designed for wide temperature ranges: cold-hardy to about -10°F (-25°C) and heat stable up to around 180°F (80°C), thanks to an anti-UV coating and heat-resistant additives in the fabric. That combination helps the cover resist cracking in winter and degradation from sun exposure in summer.

• Anti-UV coating blocking most UV exposure
• Material treated for high-temperature resistance
• Performs in freezing and hot environments without brittleness
• Double-sided waterproof surface keeps pool dry

How does the winch and cable system keep the cover secure in windy conditions?

Aibiley supplies an upgrade winch and steel cable set, with a zinc-alloy winch assembly and overstriking steel cable that resists stretching. The cable routes through reinforced grommets around the perimeter so you can tighten the cover evenly; this setup holds the cover stable during storms, high winds, and heavy snowfall.

• Zinc-alloy winch for increased tensile strength
• Overstriking steel cable for secure perimeter tension
• Reinforced grommets distribute load and reduce wear
• Designed for use in typhoon, storm, and snowy conditions

How easy is installation and routine maintenance?

Aibiley includes clear installation instructions plus the winch-and-cable kit so setup is straightforward and requires no special tools beyond the supplied components. Cleaning is simple: rinse with a hose or wipe with a damp cloth; machine washing is not recommended.

• Complete kit: pool cover, winch, cable set, instructions
• Steel-core cable threads through grommets for simple tightening
• Wipe clean with water; do not machine wash
• Customer support available 24/7 for questions
