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 |
|---|---|
| Bolted joining link | Welded kenter link has no bolt hole stress concentration and maintains full chain strength, unlike bolted links which reduce strength at the joint |
| Standard chain link | Kenter link allows for swivel rotation and is designed specifically for joining, whereas a standard link is not engineered for this purpose |
| Lugless shackle | Kenter link is a full chain connector with welded integrity, while a lugless shackle is a separate fitting that may not match chain pitch or strength |
| Rigid swivel link | Kenter link with swivel set provides a more compact and integrated solution than a separate swivel and chain link assembly |
Use Guide
How To Use And Inspect Kenter Link - Joining
- Match the stamped grade and size to the chain specification before installation
- Ensure the swivel rotates freely before and after installation to prevent binding
- Inspect the weld seam and surface finish for damage before use
- Use only with chains of matching pitch and diameter to avoid misalignment
- Do not exceed the rated working load limit stamped on the link
- Retire the link if the weld shows cracking, the swivel seizes, or the marking is illegible

Answers
Kenter Link - Joining FAQ
What is the difference between a kenter link and a lugless shackle?
A kenter link is a welded chain connector designed to join two chain lengths with full strength, while a lugless shackle is a separate fitting used to attach or connect rigging components, not intended for chain joining.
Are these links certified for marine use?
Yes, the kenter link and swivel set are available with class certificates from ABS, LR, BV, DNV, GL, RINA, KR, NK, RS, and CCS for compliance in marine and offshore applications.
Can I get a Material Test Certificate?
Yes, a Material Test Certificate to EN 10204 3.1 is supplied with each order upon request.
What surface finishes are available?
Available finishes include hot dip galvanized, galvanized, color painted, and oil. Custom finishes can be arranged.
What sizes are available?
Sizes range from 12.5mm to 162mm in diameter, with corresponding swivel diameters from 17.5mm to 403mm.
