What This Product Is For
The kenter shackle is the connecting link used to join lengths of anchor and mooring chain. It is made of two separate halves locked together by a centre chock and secure taper pin, forged from CM490 or CM690 high-tensile alloy steel in grade U2 and U3, so a chain run can be made up or repaired without welding.
Key Benefits
- Two-half design lets a chain run be joined or repaired without cutting or welding
- Centre chock and taper pin lock the halves so the joint holds under mooring load
- CM490 and CM690 materials in grade U2 and U3 to match the chain it joins
- The standard joining method across the marine industry, so crews already know the fitting
Problems It Solves
- Chain repair that would otherwise need cutting and rewelding
- Joining fittings of the wrong grade for the chain in the run
- Joints coming loose under repeated mooring loads
Application Scenarios
- Joining lengths of anchor chain
- Repairing marine chains in service
- Securing mooring system chain runs
- Chain shot assembly during fit-out

How It Compares With The Alternatives
Compared with D type joining shackle (lugged)
Both join chain lengths, the kenter uses two halves with a taper pin while the lugged type uses a lugged shackle body
Compared with Swivel forerunner
The kenter joins chain to chain, the forerunner connects chain to anchor and allows rotation
How To Use And Maintain It
- Match the kenter grade to the chain grade in the run
- Drive the taper pin fully home and secure it before loading
- Check the joint at every chain ranging or inspection
- Replace the complete shackle rather than reusing a worn taper pin
What We Need From You To Quote
- Size or diameter, and the grade if it is specified
- Quantity and packing format
- Surface finish for the environment it works in
- Classification society, if a certificate is required
- Destination port for freight
