The Rope & Float Kit includes quality rope made for swimming pools, 9 blue/white floats, stainless anchor hooks, and plastic splicing needle (to adjust rope length). The floats are made of a durable polyethylene and are sealed for optimal buoyancy. They are highly visible and treated with chlorine inhibitors as well as ultraviolet stabilizers so they will not fade or break over time. The Rope & Float Kit is available in various lengths. The size listed is the width of the pool that the rope will fit.
