PoolTree System - XL Heavy-Duty Ball Plug (Ball Sold Separately)

This Heavy-Duty Ball Plug is a genuine replacement part for both the PoolTree System V2.0 (System purchased after September 2025) and the Original PoolTree System (purchased before September 2025).

• Previously called "Oversized Ball Plug"

What’s Included:

• XL Heavy-duty Ball Plug (PoolTree Ball sold separately)

How It Works:

The XL Heavy-Duty Ball Plug fits the Extra Large Heavy-Duty Ball (this will not fit the Original PoolTree Standard Ball). 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 blows away - keeping pool maintenance simple all winter long.
