The SLB600 is a short-range buoy ready for immediate installation. Typical applications include day and night channel, speed zone and restricted area marking. The SLB600 is extremely long-lasting, and is moulded from strong, durable U.V. stabilised polyethylene. The base of the buoy is steel-shot filled, and the top section is polyurethane foam filled, providing excellent buoyancy and stability. A large mooring chain attachment point accommodates a 16mm shackle or 12mm silver rope
