JIS F2015-87 Casting Bar Type Chain Stopper

The JIS F2015-1987 Casting Bar Type Chain Stopper is a marine deck fitting that meets the Japanese Industrial Standard F2015-1987. Its primary role is to clamp the anchor chain firmly in place, prevent any unintended payout, and thus protect the entire anchoring system.

Manufactured from high-grade cast steel, the stopper sits between the windlass and the chain pipe. When the vessel is at anchor, it locks the chain and relieves most of the strain on the brake. As specified in the JIS standard, a robust hinged arm engages a chain link and halts forward motion. This straightforward mechanism combines ease of use, rapid operation, and the ability to bear heavy loads without deformation.

Suitable for various types of ships, the chain stopper is installed on the deck of the ship to effectively secure the anchor chain and relieve the overload of the windlass during anchoring operations. The chain stopper is made of high-strength casting process to ensure reliable operation even in harsh marine environments. As a leading marine equipment supplier in China, Boomarine provides various types of mooring and towing equipment.
