Polar Vortex Supreme 18 x 40 ft. Rectangular In-Ground Winter Pool Cover

Polar Vortex Supreme 18 x 40 ft. Rectangular In-Ground Winter Pool Cover is a solid navy winter cover sized for a 18 x 40 ft. rectangular in-ground pool. It helps block leaves, debris, and sunlight during the off-season while its reinforced perimeter and metal grommets provide secure attachment points.

Why choose a Polar Vortex Supreme cover?

• Solid winter cover helps keep leaves and debris out of the pool
• Reinforced perimeter helps resist stress around the cover edge
• Metal grommets and water-tube attachment points
• Approximately 5 feet of additional cover material for winter installation
• Navy cover color

What is included?

One Polar Vortex Supreme rectangular winter pool cover. Water tubes and other perimeter weights are sold separately. Rectangular covers do not include the cable and winch used with round and oval above-ground covers.

Measure before ordering

Order by the pool’s actual inside dimensions—not by the cover dimensions. Confirm the pool is 18 x 40 ft. and rectangular. Steps, raised walls, waterfalls, and other obstructions can require a different cover solution.

Important: This is a winter debris cover, not a safety cover. Do not walk on the cover or allow children or pets onto it. Follow proper winter-cover installation and standing-water removal procedures.
