Sturdy construction: The rope is made of nylon and the buoy is made of thickened high-density ABS plastic. Lightweight yet durable, it resists tearing in sunlight and water and does not fade. It has strong buoyancy, floats stably, and is reusable for a long time. Stable buoyancy and safety: Pool track markings separate lanes to avoid collisions and increase safety. The buoy absorbs wave energy, contributing to wave dissipation and blocking. Our track markings help swimmers maintain the correct swimming direction and provide athletes with a comfortable competitive environment. Highly visible colors: The white and blue color scheme is easy to spot in the water, allowing a clear distinction between the deep and flat ends of the pool and tracks. Use this safety rope and buoy as a safety marking line to ensure safety when swimming. Wide use: Pool safety ropes are suitable for separating hazardous areas, safety areas or swimming competition tracks. Mainly used in swimming pools, inland waterways, waterways, flat obstacles and other aids. Use scenarios: - In swimming pools during competitions or training to delineate lanes and keep swimmers on course. - To mark safety zones or restricted areas in pools and open water venues, reducing accidental entry. - As track markers in indoor or outdoor swimming facilities, water parks, and other aquatic venues to delineate competition routes or obstacle boundaries.
