Kenter Shackle

Definition & Function

A Kenter Shackle is a two-part D-shaped marine fitting that securely connects two chain ends via a taper pin and chock mechanism. Its reversible design enables rapid assembly and disassembly of chains while maintaining alignment under heavy loads. This type of shackle is essential in mooring systems, offshore platforms, FPSOs, and floating renewable energy installations.

Core Advantages

• High-Strength Steel: Ensures maximum load capacity for marine operations.
• Quick Connection: Two-part D-shaped halves with taper pin for fast, reversible assembly.
• Marine-Grade Durability: Resistant to corrosion and fatigue in harsh seawater environments.
• Customizable Surface Treatment: Black bitumen coating or hot-dip galvanizing available.
