Key Benefits
What Kenter Shackle - Anchor Chain Fittings Gives You
- Welded construction maintains chain strength at the connection point without reducing rated capacity
- Hot dip galvanized or painted surface resists saltwater corrosion in marine environments
- Available in U2 or U3 grade steel for high tensile strength and fatigue resistance
- Standard sizes from 12.5mm to 162mm cover most anchor chain applications
- Silver, black, or steel color finishes available to match existing chain or deck hardware
- Class certificates from ABS, LR, BV, DNV, GL, RINA, KR, NK, RS, and CCS support compliance in regulated marine projects
- One-piece welded design reduces moving parts and inspection points in high-vibration marine service
Application Scenarios
Where Kenter Shackle - Anchor Chain Fittings Is Used
- Connecting anchor chain sections on offshore supply vessels and platform support ships
- Securing mooring lines on offshore platforms and floating production units
- Reinforcing chain links in heavy-duty ship mooring systems exposed to saltwater and dynamic loads
- Integrating anchor chain fittings into marine recovery and towing systems
- Replacing worn or damaged chain links in existing anchor chains with a certified replacement shackle
- Supplying marine contractors with pre-certified chain fittings for offshore installation projects
Who It Is For

How It Compares With The Alternatives
An honest read on where this pattern wins and where another one would serve you better.
| Alternative | Honest Trade Off |
|---|---|
| Forged shackle | Welded kenter shackle is lower cost and suitable for static chain connections; forged shackle offers higher impact resistance but at higher price |
| Screw pin shackle | Welded kenter shackle has no moving pin to back out under vibration; screw pin requires regular inspection and locking mechanism |
| Rigid chain link | Kenter shackle allows for easier chain replacement and inspection; rigid link is permanent and harder to maintain |
| Non-certified shackle | This version includes class certificates from major marine classification societies; non-certified versions lack audit trail and compliance support |
Use Guide
How To Use And Inspect Kenter Shackle - Anchor Chain Fittings
- Match the stamped working load limit to the calculated chain load, not the vessel’s winch rating
- Inspect the weld seam and surface finish before installation for cracks or coating damage
- Ensure the chain size matches the shackle’s rated size to avoid overloading
- Apply oil or lubricant to the chain link before inserting the shackle to reduce friction
- Do not use if the shackle shows deformation, weld cracking, or coating failure
- Retire the shackle if the marking is illegible or if it has been exposed to extreme overload
