4 ft. x 15 ft. Ice Equalizer Pillow for Above Ground Swimming Pool Covers (2-Pack)

Ice equalizer pillows relieve stress from the walls of your pool caused by ice. They also reduce the build-up of rain water and snow on your winter cover. Simply inflate the pillow . place it under your cover . and secure it using the provided grommets during the winter months. It is prudent to not overfill the pillow with air (best practice is usually half-way to three quarters full). The Robelle Equalizer pillow is made with durable heavy duty 16-Gauge vinyl.
