What is UNAV 4203 and 4208 snap hook?

The UNAV 4203 and 4208 snap hooks are two types of hooks used for the connection between chain and chain locker.

They allow the chain to be released in case of emergency.

The 4203 snap hook, when installed on deck with the aid of suitable tensioners and shackles, serves as a holding draft to keep the anchor in position when it is in the locker.

The UNAV 4208 snap hook is more suitable for the chain locker.

Available in different finishes: galvanized, stainless steel, and painted versions.

Operational Advantages of Accessories

  • Emergency Safety: the ability to quickly release the anchor chain is crucial in critical situations (storms, grounding, emergency situations). It allows for rapid anchor release without having to go on deck in rough seas.
  • Anchor Protection in Port: the 4203 shackle, acting as a chain stopper on deck, keeps the anchor firmly secured in the hawsepipe during navigation, preventing unwanted movements that could damage the hull or create noise.
