Swimline Winter Pool Cover Air Pillows - 4.5 ft. x 15 ft.
Brand: Swimline
Ice and frozen water can cause potential damage to your above ground pool cover and pool walls due to expansion. This 16 gauge vinyl Air pillow goes under your pool cover, and protects your pool cover and walls by attracting freezing water as it expands due to water contraction. This multi-purpose pillow also helps reduce the build-up of rain, leaves or snow on your winter cover. The Air Pillow only needs to be inflated half-way to prevent deflating due to expansion. Measures: 4.5 x 15 feet.
