Swimline Winter Air Pillow – 48" x 180" Ice Equalizer for Above-Ground Pool Covers (ACC515)

Winter is hard on above-ground pools. As water freezes and expands, it pushes outward against your walls — and a cover that sags into the water collects rain, snow and ice until something gives. An air pillow solves both problems at once.

Float this one in the center of the pool before you put the cover on. It lifts the cover off the water so debris and meltwater run off to the sides instead of pooling, and it gives expanding ice somewhere to go besides your pool walls.

Key Benefits:

• Acts as an ice equalizer — expanding ice compresses the pillow instead of pressing on pool walls
• Raises the cover so rain, snow and debris slide off rather than collecting in the middle
• Keeps the cover from freezing into the water surface
• Cold-resistant vinyl built to hold up through a full winter outdoors
• 48" x 180" — sized for most round above-ground pools

How to use: Inflate to about 60–70% — a firm pillow with give, not a drum. Overinflating is the most common reason pillows split in a hard freeze. Center it in the pool, then install your winter cover over the top. A pillow pal or a length of cord tied to the cover grommets keeps it from drifting to one side.
