- Stable construction: This safety pool boundary line is made from ABS plastic and nylon with a smooth surface and a finger-safe finish. It resists deformation, tearing, and breaking; it is UV resistant and designed for long-term reuse. - High visibility colors: The buoy is blue and white, ensuring the pool boundary is clearly visible and helping swimmers respect the limit to prevent collisions or entry into restricted areas. - Stable buoyancy and safety: Lane markers separate swim lanes, reduce collisions, and improve safety. The buoys absorb wave energy, aiding wave dissipation and blocking. They help swimmers follow the correct direction and provide athletes with a comfortable competition environment. - Versatile use: Suitable for pools and pool parties, but also for marking dangerous areas, protecting loved ones while swimming, or turning outdoor spaces into training or competition lanes. Also suitable for rivers, waterways, shallow-water obstacles, and other water aids to prevent the accumulation of floating objects. - Use scenarios: Mark swim lanes in home or community pools for training or events; delineate safety zones during pool parties and keep children away from restricted areas; mark hazards in rivers or canals to prevent floating-object buildup and guide water traffic.
