Perfect for docks and marina applications, Solar Cleat Lites provide all-night illumination with their built-in charging solar panel, battery and bright LEDs. The four-hole design is easy to mount (like conventional cleats) and allows for easy replacement of the components should the need arise. With Solar Cleat Lites, there are no wires, no electrical costs and no more stubbed toes on the dock at night! Cleats are waterproof to IP 68 standard. Mount with #10 fasteners, sold separately. Made of chrome-plated zinc alloy, these cleats are best for use on docks located in freshwater. One-year warranty.
