Durable adjustable rope system for safe swim zones and clear lane marking. - Built to last: nylon rope, stainless steel hook, and PP plastic buoy resist deformation, tearing, and breakage for long service life. - High visibility: white and blue braided rope provides a clear visual cue in water, helping swimmers stay oriented. - Easy to adjust: buoy positions slide along the rope and can be moved; brackets beside each buoy let you change spacing to fit your space. - Versatile and practical: helps distinguish shallow zones from deeper water to reduce risk and can be used to create dedicated swimming lanes for training or family fun. - Quick setup and compatibility: preassembled rope for fast installation in pools, lakes, or beaches; simple to relocate or reconfigure as needed. - Suitable use scenarios: mark a kids play area near the pool edge; define swimming lanes for backyard training; create a safety boundary near a dock or jetty.
