Shackles
D-Ring Shackle With Isolator, D Ring Towing Shackles
A D-ring shackle with an integrated rubber isolator on the pin and a protective inner guard at the bow, designed to reduce noise and prevent surface wear during dynamic towing. Made from high tensile steel body and alloy steel pin, it meets EN and US standards with a 4:1 or 6:1 safety factor. Available from 3/16" to 2-1/2" with powder coating in custom colors. The isolator fits between the connection point and the shackle center to dampen vibration and protect the paint at high-stress points.

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 |
|---|---|
| Standard D-ring shackle | The isolator reduces noise and protects the paint at the bow, but adds a rubber component that may degrade under extreme heat or UV exposure |
| Shackle with external isolator sleeve | The internal guard is more effective at protecting the bow surface and prevents debris from entering the gap, but requires more precise assembly |
| Screw pin shackle | The bolt pin with nut is more secure under vibration than a screw pin, but requires a wrench for tightening |
| Rigid shackle without protection | The isolator reduces wear and noise but adds weight and may need replacement over time under harsh conditions |
Use Guide
How To Use And Inspect D-Ring Shackle with Isolator
- Verify the stamped working load limit matches the intended load, not the winch rating
- Ensure the rubber isolator is properly seated and not cracked or compressed
- Tighten the pin nut securely before each use, especially under dynamic loads
- Inspect the inner guard and isolator for wear or displacement after each operation
- Do not exceed the rated capacity or use in side-loading situations
- Replace the shackle if the body shows deformation, the isolator is damaged, or the marking is unreadable
