A shackle is a safety-critical link in any anchoring setup. The cromox® Nautic shackle is designed for reliable connections on board, for example between anchor and anchor chain. Built from AISI 318LN Duplex stainless steel and finished with a shot blasted surface, it is made for long service life in salt water environments.
The cromox® Nautic shackle is a stainless-steel quick connection shackle designed to be robust and dependable in marine use. It provides a secure connection between two components where failure is not an option, such as the interface between anchor and chain.
A key functional benefit is the pin security concept. The pin is designed to be doubly secured against becoming loose. When secured, it can still be rotated, enabling a flexible yet reliable connection in practical on-board handling.
The Nautic shackle combines material selection with a safety-focused locking concept. In marine applications, corrosion resistance is critical because moisture and seawater constantly attack exposed metal surfaces. Stainless steel resists corrosion through a passive surface layer that helps protect the material over time.

The cromox® NAUTIC Shackle is designed to create a secure connection between critical components in an anchoring system, such as the anchor and anchor chain. It is intended for applications where a reliable connection is essential for safe operation.
The cromox® NAUTIC Shackle is manufactured from AISI 318LN Duplex stainless steel. This material is selected for its strength and corrosion resistance in marine environments.
The shackle features a double safety concept at the pin, which is designed to reduce the risk of accidental loosening. When properly secured, the pin can still be rotated to support practical handling during installation and use.
Marine shackles are continuously exposed to seawater and moisture. Corrosion-resistant materials help maintain the integrity of the connection over time and support long-term use in demanding marine conditions.
The cromox® NAUTIC Shackle features a shot blasted surface. This finish is designed to support durability and long service life in marine environments.
The shackle is designed for safety-critical marine connections, including the connection between an anchor and an anchor chain. It can also be used wherever a robust and secure stainless-steel connection is required on board.
The combination of AISI 318LN Duplex stainless steel, a shot blasted finish, and the double-secured pin concept is designed to provide a robust and dependable connection within the anchoring system.
The anchor-to-chain connection transfers the loads generated throughout the anchoring system. For this reason, the connection component must be designed to provide a secure and reliable link between both elements.
