Product Description The 4' x 4' Ice Equalizer Pillow relieves stress from the walls of your pool caused by ice. Ice Equalizer pillows also reduce the build-up of rain water, leaves and snow on your winter cover. All you have to do is inflate the pillow and 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. Safety Warning Do not overfill the pillow with air. Use with pool covers as instructed. Keep away from heat sources and sharp objects to prevent damage.
