This item is a marine-grade anchor chain lock (also frequently called a chain claw, chain stopper, or snubber hook). It is typically cast from heavy-duty 316 stainless steel to withstand corrosive saltwater environments.
Primary Functions
Relieves Windlass Tension: It transfers the extreme strain of a deployed anchor away from the boat's mechanical anchor winch (windlass) and redirects it safely to a heavy deck cleat or mooring bridle.
Reduces Noise: Securing the chain with a snubber line eliminates the metallic grinding and clanking sounds of the anchor chain rubbing against the bow roller while the boat rides waves.
Acts as a Shock Absorber: When attached to a flexible nylon line (a snubber), it absorbs the sudden shocks from waves, preventing the anchor from being jerked loose from the seabed.
How It Works
1,The Slot: The narrow vertical channel in the center slides right over a vertical link of the anchor chain.
2,The Funnel/Flanges: The angled sides cradle the adjacent horizontal link of the chain, wedging it firmly in place without twisting or damaging the links.
3,The Top Loop: A dedicated nylon snubber line or shackle is tied through the large round top eyelet.
