Corrosion-Resistant Anchor Chain Shackles Certified For Marine And Offshore Applications

In marine applications, as shackle is an essential piece of equipment that joins anchor chains, anchors and other mooring devices. Shackle for Anchor Chain serves as the crucial component that guarantees the chain system’s dependability under heavy loads at sea. As one of the trusted marine hardware manufacturers and suppliers in China, our factory produces a wide range of Shackle for Anchor Chain that comply with international standards. We’ve been delivering quality marine supplies for three decades, we’re confident that our products meet the needs of industry.

What does a shackle do?

A shackle's job is simple but essential:it joins different sections of the anchor chain or links the chain to the anchor itself, providing flexibility, safe load transfer and safe disassembly when required. Anchor chain would not be modular without shackles, which would make installation, maintenance and repair much more difficult.

How many types of shackles do you offer?

We provide a wide variety of shackle for anchor chains, including all the major type that shipbuilders and offshore operators need. These include:

Kenter Shackle: for connecting chain lengths with high reliability.

End Shackle: unsed to secure the chain to the anchor.

Joining Shackle: made to firmly connect two chains.

Buoy Shackle Type A and Buoy Shackle Type B: for buoy mooring applications.

Swivel Shackle Type A and Swivel Shackle Type B: allowing free rotation to prevent chain twisting.

To ensure flawless compatibility, each type is produced in range of diameters to match studlink or studless anchor chains.

Why are shackles needed?

Shackles are essential to the marine industry because they offer the flexibility and adaptability that chains alone cannot offer. A Kenter Shackle, for exanple, makes it possible to quickly assemble along chains on board, and Swivel Shackles keep chains from kinking and compromising anchoring safety. Buoy Shackles make offshore buoy mooring secure and efficient. In all situations, using shackles extends the chain system’s life, lowers operational risks and makes handling the chain during inspections or replacement simpler.

Do you offer certificates for shackles?

Yes. We craft all of our shackle in accordance with major classification societies, such as CCS, ABS, DNV, BV, LR, NK, KR, RS, and RINA. We provide certificates to confirm adherence to maritime standards, guaranteeing that your goods are promptly approval by ship registries across the globe.
