Key Benefits
What Twin Clevis Link S249 H Link Gives You
- Quick connection between chain and attachment points using a simple jaw clevis, pin, and cotter
- Forged carbon steel body provides strength and impact resistance for heavy-duty rigging
- Alloy steel pin and cotter resist deformation under repeated loading and vibration
- H-type design allows two chain ends to be linked in a single fitting, reducing the number of components
- Standard 4:1 safety factor ensures reliable performance under working load conditions
- Galvanized, self-color, or powder coated finishes resist corrosion in harsh environments
- Compact design reduces bulk in tight rigging setups where space is limited
Application Scenarios
Where Twin Clevis Link S249 H Link Is Used
- Connecting Grade 30 or Grade 43 chain to a pad eye or tractor eye bolt on a construction site trailer
- Linking two chain segments in a temporary rigging setup for equipment anchoring
- Securing a load to a fixed point using chain and a clevis link in a material handling system
- Field assembly of chain assemblies where quick connection and disassembly are required
- Linking chain to a ring or end link in a non-overhead lifting application such as a ground anchor or tie-down
Who It Is For
Buyers This Product Is Built For
- Construction site rigging teams needing fast, reliable chain connections
- Industrial maintenance crews assembling temporary chain systems for equipment handling
- Truck and trailer operators securing loads with chain and clevis links
- Rigging distributors carrying a range of chain accessories who need a standard link with multiple finishes

Problems It Solves
Problems This Product Removes
- Requiring multiple separate links to connect chain to a ring or eye bolt, increasing setup time and part count
- Using a weak or mismatched connection that fails under dynamic load or vibration
- Lack of a standard H-type clevis link that allows two chain ends to be joined in one fitting
- Chain ends not aligning properly due to rigid or poorly designed connectors
- Corrosion damage in outdoor or wet environments due to uncoated or low-grade steel
- Need for a quick-release connection that can be assembled with hand tools in the field

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 |
|---|---|
| Single clevis link | The twin clevis link allows two chain ends to be joined in one fitting, reducing part count and assembly time |
| Screw pin link | The cotter pin design is more secure under vibration and dynamic load, but requires more effort to install than a screw pin |
| Rigid chain link | The clevis design allows for easier alignment and connection, but has a lower strength-to-weight ratio than a solid forged link |
| Welded link | The forged body provides better impact resistance and fatigue life than a welded link, but is more expensive to produce |
Use Guide
How To Use And Inspect Twin Clevis Link S249 H Link
- Match the stamped working load limit to the calculated chain load, not to the equipment rating
- Ensure the chain is fully seated in the clevis jaws before installing the pin and cotter
- Torque the pin and install the cotter pin correctly to prevent loosening under vibration
- Inspect the link before each use for deformation, wear, or damage to the pin or body
- Do not use for overhead lifting or hoisting — this link is not rated for vertical lifting
- Retire the link if the body shows deformation, the pin is bent, or the marking is no longer legible
