Chain Stopper for 6–10 mm Anchor Chains — Marine-Grade Stainless Steel, Bow Roller Compatible

The Chain Stopper from Absolute Marine is a precision-crafted safeguard designed to protect your windlass and streamline mooring operations. Engineered to integrate with your bow roller, it securely locks the chain to relieve windlass tension once you’re anchored, dramatically reducing wear and the risk of gear damage during tensioned mooring and at anchor.

Key benefits at a glance

• Marine-grade stainless steel construction delivers reliable corrosion resistance in saltwater environments, ensuring long-term performance in demanding marine conditions.
• Chain compatibility up to 10 mm, covering the common sizes used on a wide range of boats (6, 7, 8, and 10 mm chains).
• Removable SS pin enables easy insertion of the chain into the channel, making installation quick and straightforward—even as a retrofit to existing setups.
• Dual-position stopover flip offers two modes: a free-flow condition for smooth chain feeding, and a locked mode to securely hold the chain when needed.
• Simple retrofit design that can be added to most existing bow roller installations without major modifications.
• Proactively protects your windlass by taking the strain during tensioned mooring and at anchor, helping extend the life of critical hardware.
• Enhanced security at anchor and during mooring provides peace of mind for everyday use or heavy-weather conditions.

How it works

Insert the chain into the channel via the removable pin. When you’re ready to pay out or retrieve chain, flip to the free-flow position for unrestricted feeding. When securing the mooring or anchoring, flip to the locked position to hold the chain firmly in place and relieve windlass stress.
