This Standard Ball is a genuine replacement part for the Original PoolTree System (System purchased before September 2025). If your system uses ropes, this is the correct version. If your system uses nylon straps, you have the PoolTree System V2.0 → find those replacement parts here. COLORS MAY VARY. The PoolTree Ball is used to support the center of the PoolTree System holding the cover out of the water. Must be used with the standard harness. This unique system will not pop or move out of place like common pool pillows, even under the heaviest snow loads. NOTE: This is ONLY for the standard ball (standard harness sold separately).
