Sea-Dog Rubber Mooring Snubber, 5/8 to 3/4 Inch Line, 21-1/2 Inch Length

The Sea-Dog Rubber Mooring Snubber (part number 561520) absorbs shock loads and relieves tension on dock lines and deck fittings, protecting cleats, chocks, and line ends from the repeated jerking caused by wind, wake, and current. It is sized for line diameters of 5/8 inch to 3/4 inch and measures 21-1/2 inches in length. In use, the snubber is threaded onto the mooring or dock line and the amount of compensating stretch is adjusted simply by changing the number of turns the line makes around the snubber body, letting the same unit be tuned for light chop or heavier surge conditions.

No additional hardware, clips, or tools are needed to install or adjust it, so it can be fitted or repositioned on the line in minutes. It is built from high quality rubber engineered to resist sunlight, saltwater, and ozone exposure, making it suited to long-term outdoor use. This makes it a practical choice for boats on exposed moorings, in tidal areas where line tension changes with the water level, and in towing situations where sudden loads are common.
