1. STABLE CONSTRUCTION: This pool partition is made of high density ABS, which is stable and strong, not easily deformed, cracked or broken, UV resistant and can be used for a long time. Nylon rope has high strength, low density, good stability, high tension and strong load bearing capacity. 2. STABILITY AND SAFETY: The buoyancy coefficient is stable and the anti interference strength is strong. The scientific design effectively reduces the interference of water waves in each lane and reduces resistance. It can float stably on the water surface and provide athletes with a good competition environment. 3. POOL DIVISION ROPE: 1 m/3.3 ft buoy rope has 2 buoys, each buoy has a diameter of 7 cm (2.76 inches). The length of the pool buoys is 1 m – 18 m (3.3 ft – 59 ft). 4. Highly visible colors: The blue and white buoy is easy to spot in the water and can clearly distinguish the deep and shallow ends of the pool and the lanes. Use this rope and buoy as a marking line to ensure your while swimming.
