End Shackle

The CSAC Chain Manufacturer's End Shackle—also known as a Type D anchor end shackle—is a core connecting component within anchoring systems. Primarily used to link the anchor's crown shackle to a swivel or anchor chain assembly, it serves as the critical component for transmitting tensile forces between the anchor chain and the anchor body, thereby directly influencing the stability and safety of the entire anchoring system.

During ship anchoring operations, the End Shackle must withstand various external forces—such as the tensile loads exerted by the vessel amidst wind and waves, as well as the impact forces of water currents—while simultaneously resisting the corrosive effects of seawater. Consequently, its quality and performance are directly tied to the navigational safety of the vessel. Our End Shackles are engineered with precision and subjected to rigorous testing; they provide a stable connection between the anchor chain and the anchor body, ensuring the anchoring system functions reliably across a wide range of complex marine environments and preventing safety incidents caused by connector failure.

Key Product Features

• Stable Structure: Utilizing robust elliptical cross-section pins, coupled with positioning safety pins for secure fixation, effectively preventing accidental loosening, enhancing safety, and adapting to the needs of long-term, high-frequency mooring operations.
• Superior Material: Forged from high-quality steel, it possesses excellent strength and durability, can withstand significant tensile forces, and is not easily deformed or broken, making it suitable for harsh marine working conditions.
• Full range of specifications: sizes range from 12.5mm to 162mm, with standard sizes ranging from 14mm to 122mm, which can be flexibly adapted to different sizes of anchor chains and anchor bodies to meet the needs of various ships and marine engineering projects.
• Corrosion resistant and durable: Two optional processes are available: hot-dip galvanizing and black asphalt coating, which effectively improves the product's corrosion resistance in seawater environments, extends its service life, and reduces maintenance costs.
• Controllable quality: Every End Shackle product undergoes rigorous testing, including non-destructive testing, verification tests, and load tests, before leaving the factory to ensure that the product performance meets international standards and provides greater peace of mind.
