How It Compares With The Alternatives
Compared with D-type shackle G210
The G209 bow body takes angled and multi-leg loads, the G210 dee body is for two-directional in-line pulls

The G209 screw pin is quicker to connect, the G2130 bolt and nut version is for long-term or permanent installations
How To Use And Maintain It
- Confirm the WLL stamped on the shackle covers your load before use
- Seat the screw pin fully and check it has not backed out during service
- Use Dacromet or powder coating where galvanizing will not survive the environment
- Retire any shackle with a bent pin or damaged threads
