$44.99

What’s Included:
- Extra Large Heavy-duty Ball (PoolTree Ball Harness sold separately)
How It Works:
The Extra Large Heavy-Duty Ball is secured in place with the PoolTree ball harness, which connects to the long nylon support straps. Unlike common pool pillows, the ball & harness will not pop, deflate, or shift out of place - even under heavy snow loads. Supported by the StretchConnect Assemblies, the ball & harness keep your cover raised above the waterline so rain & snow drains through and debris dries and blows away - keeping pool maintenance simple all winter long.
