9″ Smooth rolling wheels offer substantial dock cushioning and feature
molded-in valves to adjust the level of firmness. Heavy-duty hot-dipped
galvanized hardware mounts securely to the dock. Guides boats into your
slip easily, regardless of wind and current conditions.
Integrally molded ribs on both the top and bottom of these wheels make them
valuable dock and boat protection and formidable guards against impacts.
