Chain Stopper, AISI 316 Stainless – for Ø6-8 mm Chain

This stainless steel chain stopper (small size for 6–8 mm chain) is an ideal addition for smaller boats and runabouts aiming to improve their anchoring safety. It is built from high-quality 316 stainless steel, ensuring reliable performance without rust over time. Mounted on the deck near the bow roller or windlass, the stopper allows the chain to be easily secured once the anchor is dropped.

Using a hinged pawl or hook mechanism, the device locks onto a chain link to prevent any unwarranted further payout of chain. This removes the strain from the windlass and protects it from overload – a crucial benefit in breezy conditions or during long periods at anchor. For small to medium vessels (e.g., 5–8 m boats) using 6–8 mm chain and anchors up to ~15 kg, this stopper greatly increases confidence when anchoring overnight or in open water. When you’re ready to weigh anchor, simply release the stopper and resume winching in the chain – the process is quick and straightforward. Investing in a chain stopper extends the life of your windlass and chain by shielding the mechanical parts from shock loads and provides peace of mind while anchoring.
