Snubber - 3/8" - Rubber 

Mooring Snubbers absorb shock loads and relieve tension on lines and deck fittings. The length of compensating movement can be adjusted by the number of line turns around the snubber, mitigating the effects of wind and waves. Easy to use, requiring no extra hardware. Ideal for use in tidal areas, on exposed moorings, or in towing situations. Constructed of high-quality rubber to resist sunlight, saltwater, and ozone.
