Stud link anchor chains are a type of heavy-duty chain commonly used for anchoring and mooring vessels. They have a central stud in each link that helps to prevent kinking, deformation, and fouling. These chains are known for their strength and are often preferred for large vessels and applications where significant loads are involved.
Fishing chains have three specifications: short link chian, middle link chain and long link chain. Different types of fishing chains have different features.
Studless Fishing Anchor Chain are 62.5% load verified at break, very durable and able to withstand extreme and harsh weather use, it is also corrosion-resistant, ideal for use in saltwater environments. There are Short Link, Mid Link and Long Link to choose from.

The Stingray Anchor is a high-efficiency drag embedment anchor designed for aquaculture and marine mooring. With holding power exceeding 40 times its own weight, it significantly outperforms conventional anchors of similar size.
The Sand Anchor has is a conventional anchor with solid construction to withstand high load.It has high holding power and weight ratio and very suitable for seabed of sand and mix Soil.
Mooring connection plates are manufactured using alloy grade material and followed by full heat treatment process.The durability ensures that the plates can withstand exposure to saltwater, reducing maintenance needs and extending the lifespan of the aquaculture setup.
Rope K3 Thimble is used for aquaculture mooring, where the surface needs to be heat-treated to protect wire, fibre or synthetic ropes.
The 12.5mm Stud Link Anchor Chain is a heavy-duty marine chain primarily used in ship anchoring and mooring systems. Standard length (short link): typically supplied in 27.5-meter (15 fathom) lengths, connectable using Kenter shackles.
AM3 is a designation for a grade of stud-link anchor chain, specifically referring to a high-strength steel chain used for ship anchoring and mooring. These chains are designed for durability and reliability in demanding marine applications, often used on large vessels or in harsh environmental conditions.
Stud link anchor chain AM2 is a specific type of anchor chain widely used in marine applications. It's characterized by having a stud (a crossbar or bar) within each link, adding strength and preventing kinking or twisting. AM2 is a designation within the marine industry for a specific grade of this chain, indicating its strength and material properties.

An end shackle (ES), also called an anchor shackle (AS), is used to connect the anchor chain to the anchor itself – it is the final link between the chain and the anchor.
The term "end shackle" describes its position (at the end of the chain), while "anchor shackle" describes its function (connecting to the anchor).

1.Are end shackle and joining shackle the same thing?
No, they are not the same.
An end shackle (ES), also called an anchor shackle (AS), is used to connect the anchor chain to the anchor itself – it is the final link between the chain and the anchor.
The term "end shackle" describes its position (at the end of the chain), while "anchor shackle" describes its function (connecting to the anchor). Both names refer to the same component.
End shackles and joining shackles are not interchangeable. Always use the correct shackle type for each position in the anchor chain system.
2. What is the function of an end shackle and where is it installed?
An end shackle is used to connect the final link of the anchor chain to the anchor ring or crown. It serves as the critical connection between the vessel's anchor and the anchor chain.
It is installed at the very end of the anchor chain, just before the anchor. This is the shackle that takes the full load of the vessel when at anchor, making it one of the most heavily stressed components in the entire mooring system.
3. What are the size and weight differences?
An end shackle is larger and heavier than a joining shackle.
For the same chain diameter, an end shackle has a diameter of approximately 1.4d and is noticeably heavier than a joining shackle (which has a diameter of approximately 1.3d). For example, at 22mm chain size, an end shackle weighs about 3.9kg, while a joining shackle weighs about 2.6kg.
This extra size and weight are intentional – the end shackle must withstand the shock loads, abrasion, and constant stress of holding the vessel's anchor in position, often in harsh sea conditions.
4. How does an end shackle connect to the chain?
An end shackle typically connects directly to the anchor ring at one end and to a swivel or connecting component at the other end.
An end shackle provides a more direct connection to the anchor. In many configurations, a swivel is installed between the end shackle and the chain to prevent twisting.
5. Does an end shackle pass through the windlass gypsy wheel?
Generally no – and this is an important distinction.
Unlike a joining shackle, which must travel through the windlass during chain extension and retrieval, the end shackle is typically stopped at the chain stopper or hawse pipe when the anchor is fully housed.
This is why different shackle types exist – each is designed for its specific position and function in the anchor chain system.
