1. What is a 3-Link Adaptor ? It is a flexible 3-link assembly used at the end of an anchor chain​ to provide an open end link for connecting to shackles, swivels, or other fittings. It bridges the chain to the anchor side or to the chain locker end fastening.

The 3-Link Swivel Assembly (also known as a Swivel Forerunner) is a compact anchor chain component designed to prevent twisting and kinking during deployment and retrieval. It consists of an End Link (E), a Swivel (SW), an Enlarged Link (EL), and a Common Link (C) – a standard configuration widely used in marine mooring systems.

Swivel shackle is a marine accessory, specifically a chain link, which is a chain with a fixed structure, which is composed of 5 parts: End Link, Enlarged Link, Swivel Shackle, Enlarged Link, Common Link. And it is used to make the anchor chain avoid twisting during lifting anchors.

The Pear Shaped Shackle Grade 3 is a detachable anchor chain connector designed to link the swivel end of a chain cable to the anchor crown shackle. Unlike standard joining shackles, it features a tapered, pear-shaped profile — a wider rounded end for pin insertion and a narrower tip for easy load attachment.

A Kenter link shackle, or Kenter joining shackle, is a type of detachable link used to connect two lengths of stud-link chain, typically in the marine industry. It's composed of two halves that are connected by a center stud and a locking pin, often a tapered pin with a lead plug. This type of shackle is used to join anchor and mooring chains.

An Anchor Shackle End Shackle is a specific type of shackle used in marine applications, particularly for connecting anchor chains. It's a D-shaped fitting with a removable pin, designed to safely connect the anchor's standard shackle to the chain or to a rope with a thimble.

The End Link is a specialized connecting component used in anchor chain systems. It serves as a transition fitting between the enlarged link and the end shackle or swivel within an anchor chain assembly. The End Link is an open-type link with enlarged diameter. Its size ratio is 1.2d, where d represents the diameter of the common link. Surface finish options include black bitumen coating and hot dip galvanized. Material grades available are U2 for standard applications and U3 for higher tensile strength requirements.

The anchor chain jioning shackle, also known as the anchor shackle or anchor chain shackle, is a connecting device used to connect the segments of anchor chain and is a key component in the maritime and offshore industries. It is an important part of the anchor system, ensuring that the anchor is firmly fixed to the anchor chain.

Forelock shackle is designed for use within stud link anchor chain as a means of connecting the stud link anchor chain to an associated fitting, termination point or in a navigation buoy mooring bridle system.

A Marine Anchor Chain Swivel is a piece of marine hardware that connects the anchor to the anchor chain, preventing the chain from twisting or kinking as the boat moves or the anchor is deployed and retrieved. This device allows the anchor to be retrieved and stowed smoothly, reducing wear and tear on the chain, deck gear, and bow roller.

A marine swivel shackle, specifically a "Type B," is a connecting link used in marine applications to connect the anchor chain to the anchor. It functions as both a swivel and a shackle, allowing the chain to rotate freely to prevent twisting and damage. Type B shackles are designed to connect directly to the anchor shackle and anchor shank.

A marine swivel shackle, specifically a "Type A," is a connector used in anchoring systems to join the anchor to the chain, allowing for free rotation and preventing twisting or kinking of the chain. This type of shackle is designed to be compact and minimizes the space between the anchor and the chain.

The Quick Release Buoys Hook can be operated hydraulically by a single push-on-a-button. This allows the hooks to be released from a distance, individually or simultaneously in case of an emergency with a PDA or from ashore with a control panel.

A marine chain grapnel hook is a tool used to recover lost or detached anchor chains or anchors that have fallen to the seabed. It's designed with flukes that grip the chain links, allowing the hook to be pulled back to the surface, retrieving the anchor and chain.

A "Chain tensioner Dogbone Shackle" is a type of chain tensioner that uses a shackle-like mechanism to adjust the tension of a chain, often found in applications like tire chains or for joining heavy chains. It's characterized by a "dogbone" or "U-shaped" design, with two ends that can be opened and closed to grip the chain. The "double type" refers to a version with two of these shackle mechanisms, allowing for more adjustment and control over chain tension.
