Marine Shackle
Introduction:
A marine shackle is a type of hardware used to connect different parts of a ship's rigging or other equipment that is used in a marine environment. It is typically made from a sturdy metal such as stainless steel, and is designed to resist the corrosive effects of salt water and other harsh conditions.
Marine shackles come in various sizes and shapes, including D-shackles, bow shackles, and screw pin shackles, each with its own specific uses and advantages. They are often used to connect chains, ropes, and other lines to anchors, buoys, or other objects.
One of the primary features of a marine shackle is its strength, as it must be able to withstand the forces and stresses that are common in marine applications. Additionally, marine shackles often have a special pin or locking mechanism that prevents accidental disconnection or loosening, providing an added level of safety and security.
Overall, marine shackles are an essential component of many marine applications, providing a reliable and durable connection point for various rigging and equipment needs..

How to Choose Suitable Shackles for Anchor Chains?
1. Make sure the shackles' size based on the nominal diameter of anchor chain;
2. Shackles' grade should be the same as anchor chains' grade;
3. Using Kenter shackles when anchor chain length(C+C+...+C+C), using D type joining shackles when chain length(E+EL+C+...+C+EL+E).
