What is Devil’s Claws Chain Stopper
Anchoring a ship may look simple, but anyone in the maritime industry knows the weight of responsibility it carries—literally. The anchor chain handles enormous loads, and the windlass alone can’t bear it all. That’s where the Devil’s Claws Chain Stopper comes in. By gripping the chain links securely, it takes the load off the windlass, keeping the vessel safely anchored even in rough seas. It’s a small device in size, but its impact on safety and efficiency is huge.
Applications Across Vessel Types
Devil’s Claws Chain Stopper are widely used across a variety of vessels, from offshore support boats to large container ships and tankers. Installed on the deck between the windlass and the hawse pipe, the stopper grips the anchor chain during deployment, holding the vessel securely in place. When the anchor is raised, the stopper is released to allow the chain to move freely, providing reliable, controlled operation every time.
Specifications and Standards
Covering chain diameters from 22 mm to 76 mm, Devil’s Claws Chain Stoppers support working loads from 40 to 450 tons. Constructed from high-strength or alloy steel with corrosion-resistant coatings, they are engineered for durability in demanding marine environments. Fixed, swing, and adjustable configurations are available, with certain models offering fine-tunable claws to accommodate varying chain link sizes, delivering both flexibility and reliable holding performance. All units comply with factory acceptance tests and follow international standards, ensuring dependable operation and broad applicability across vessel types.

How to Use Devil’s Claws Chain Stoppers
Claws Chain Stoppers are installed on the deck between the windlass and the hawse pipe, providing a secure point to hold the anchor chain. During anchoring, the stopper’s claws engage the chain links, taking the load off the windlass and holding the vessel in place. When raising the anchor, the stopper is released to allow the chain to move freely through the device. Adjustable models can be fine-tuned to match specific chain diameters, ensuring a secure grip without damaging the links. Regular inspection and lubrication of moving parts are recommended to maintain smooth and reliable operation in harsh marine conditions.
