Product Detail

What Is A Shackle On An Anchor?

A shackle on an anchor refers to a specific type of connecting device used to attach the anchor to the anchor chain or anchor line. It is a metal link with a curved or U-shaped design, typically made of high-strength materials such as steel or stainless steel.

The marine shackles serve as a critical component in the anchoring system, providing a secure and reliable connection between the anchor and the chain or line. It allows for easy attachment and detachment, facilitating the deployment and retrieval of the anchor.

The design of a anchor shackle typically includes a threaded pin or bolt that passes through the openings or eyes on the anchor and the chain or line. This pin or bolt is then secured with a nut or cotter pin to ensure a tight and stable connection.

Marine shackles used on anchors are often designed to withstand high loads and harsh marine conditions. They are typically manufactured to meet specific standards and requirements to ensure their strength, durability, and resistance to corrosion.
