Pool Mate 4 ft. x 5 ft. 3-Pack Classic Pool Pillow for Winterizing Above Ground Pools, .22 MM Thick Vinyl, Reinforced Grommets, Winter Pool Pillow

The Pool Mate deluxe winterizing air pillow absorbs stress created by ice building up in your pool. As ice expands in your pool the pressure created is exerted onto the pillow instead of the walls of your pool. Ice Equalizer pillows are an essential way to protect your pool during the winter. The pillow will pop before the ice damages your pool. Ice Equalizer pillows also reduce the build-up of rain water, leaves & snow on your winter cover. All you have to do is inflate the pillow & place it under your cover during the winter months. Do not overfill the pillow with air, as this can cause the valve to pop out during the winter months (1/2 to 3/4 full is recommended). smaller Equalizer pillows are recommended for round pools & larger Equalizer pillows are recommended for Oval pools. Using additional pillows will protect your pool if one fails. Using additional pillows may require a larger than expected pool cover size.
