It’s a solid (non-permeable) cover with a four-foot overlap to ease installation and help the cover float loosely on the water. The package includes a winch and cable routed through perimeter grommets for anchoring; optional accessories such as cover clips, cover wrap and water weights can improve fit and stability around decks.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this cover stay secure through winter storms?\u003c\/h3\u003e\n\u003cp\u003eRobelle supplies a winch and cable that thread through reinforced grommets to cinch the cover around the pool.
