The WTB-1020 Equalizer Pillow is a 4.5 ft. by 15 ft. air pillow to be used with Above Ground Pool Winter Covers.
The 4.5 x 15 ft large air pillows are used after closing your and covering your above ground pool:
- to make it easier to remove pooling water and debris
- when your pool water freezes, an air pillow compresses to relieve pressure on your pool walls
- to lift your winter pool cover out of the water to prevent it from freezing in the water
