This Ball Harness is a genuine replacement part for the PoolTree System V2.0 (System purchased after September 2025). If your system uses nylon straps, this is the correct version. If your system uses ropes, you have the Original PoolTree System → find those replacement parts here. What’s Included: Ball Harness (PoolTree Ball sold separately) How It Works: The Ball Harness secures the PoolTree ball and connects it 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.
