Durable, safe boundary and lane rope for pools and open water Key benefits Built to last: Heavy-duty nylon rope, stainless steel hook, and PP plastic buoys resist deformation, tearing and breakage for long service life. Adjustable layout: Each buoy can be moved along the rope and locked in place with an internal clamp beside the buoy, so you can set spacing to match your needs. Swimmer safety: Buoy surfaces are smooth and pleasant to the touch to minimize the risk of cuts when contacted in the water. Multi-functional: Clearly separates deep and shallow areas to reduce accidents and can be used to create swim lanes for training or recreational use. What it does and why you need it Provides a visible, durable boundary that improves swimmer safety and helps organize water space. Adjustable buoys let you customize spacing for lane marking, crowd control, or hazard delineation without special tools. Robust materials ensure reliable performance in pool and open-water environments. Materials and performance Rope: Nylon — flexible, strong, and resistant to wear. Hook: Stainless steel — corrosion-resistant and secure. Buoy: Polypropylene (PP) plastic — impact-resistant and maintains shape. Buoys include internal clamps next to each unit for secure, repeatable positioning. Practical applications Pool lane creation for swim practice, lessons, or lap swimming. Marking the transition between shallow and deep water at beaches, lakes or public pools to reduce accident risk. Temporary boundary or hazard marking for docks, waterfront events, or training zones. Reliable, easy to use, and focused on safety — a practical solution for clear water separation and organized swim areas.
