Roto –Lock floats are the prefect way to help establish boundaries in the water and keep your swimmers safe. The floats are made of linier polyethylene treated with ultraviolet stabilizers and chlorine inhibitors to ensure that the color of the floats won’t fade. Featuring a novel design, these floats eliminate the need for costly locking devices. Easy to assemble, just slide the float onto the rope and twist it until it’s locked. Roto-Lock floats are great safety equipment to use at pools, water parks or lakes.
