Abstract: A fence system is provided for use in conjunction with an above-the-ground flexible wall swimming pool having a liner with an upper rim defining a closed area and a plurality of spaced supports each having a lower end in engagement with the ground and an upper end connected to and supporting the liner upper rim. The fence system includes at least two spaced apart and elongated struts wherein each strut has a first end and a second end. A hanger is secured to each strut adjacent its first end and this hanger is dimensioned to fit over and be supported by the upper rim of the liner. A fastener assembly secures the second end of the strut to one support while a fence section is secured to the first ends of the struts so that the fence section extends upwardly from the upper rim of the liner.
