Marine-Grade Anchor Chain Accessories: Shackles, Swivels, and Mooring Components

CSAC Chain (zggys) specializes in providing highly reliable anchor chain accessories for the global shipping and offshore engineering sectors. Our Swivel Shackle Type B product combines the rotational capability of a swivel with the connecting function of a shackle, serving as a critical component for preventing anchor chain kinking and safeguarding the integrity of mooring systems.

As a distinguished manufacturer, CSAC Chain introduces the Swivel Forerunner (Swivel with 3 links). Featuring the configuration E + SW + EL + C and covering diameters ranging from 12.5mm to 122mm, its primary function is to prevent anchor chain twisting during anchoring operations. Strictly compliant with ISO and IACS standards, this product is suitable for use on vessels, offshore platforms, and naval equipment.

CSAC Chain supplies the Swivel Forerunner (Swivel with 4 links) for marine anchoring systems as a reliable chain connector used between anchors and stud link anchor chains. As a professional China manufacturer and supplier, Zhoushan Zhongnan Anchor Chain Co., Ltd provides swivel forerunners with diameters ranging from 12.5 mm to 122 mm. The assembly is designed to reduce chain twisting and improve smooth anchor deployment and retrieval.

In extreme navigation environments or emergency situations requiring immediate avoidance, the ability to rapidly and safely release the anchor chain is critical to safeguarding the lives of the crew and the vessel's assets. CSAC Chain provides global ocean-going vessels with a reliable Water Tight Swivel Type Anchor Releaser; this device not only boasts superior watertight performance but also integrates a swivel function, ensuring that the anchor-releasing operation proceeds smoothly and without obstruction during critical moments.

The CSAC Chain supplier's Chain Locker Eye Ring Type A is typically welded to the chain locker bulkhead and serves as the fixed attachment point for the inner end of the anchor chain. It is designed to withstand approximately 15%–30% of the chain’s breaking load, which allows the ship crew to quickly slip the chain in emergency situations. This design makes it a commonly used safety component on commercial vessels, offshore ships, and naval fleets.

The CSAC Chain is a professional marine hardware supplier in China. We provide high-strength Chain Locker Eye Ring Type B, designed for secure fastening of anchor chains inside the vessel’s chain locker bulkhead. Built with sturdy stiffening plats and made from marine-grade steel, these securing devices are reliable under load. Easy to release quickly in emergencies, and resistant to corrosion over time.
