Rigging Hardware Guide: Shackles, Snap Hooks, Swivels, Rings and Eye Bolts
2 min read OSAK
A rope system is only as strong as its weakest connection. Choosing the right fitting determines both safety and ease of installation. The table below summarises the most commonly used fittings.
| Fitting | What is it for? | Watch out |
|---|---|---|
| D shackle | Joins rope eyes, chains and turnbuckles in an in-line pull | Tighten the pin fully; secure with wire under vibration |
| Bow shackle | Connections loaded from different angles | Must be WLL-marked for lifting |
| Snap hook | Quick connect/disconnect | Never for lifting or carrying people |
| Screw-lock snap hook | Swinging, vibrating connections | Close the sleeve every time |
| Swivel | Prevents twisting and tangling | Operate in line with the load axis |
| Welded ring | Gathers several lines at one point | For general connection only |
| Ring eye bolt | Anchor point on walls, ceilings and timber | Use an anchor/nut suited to the base material |
| Turnbuckle | Tensions rope or wire and takes up slack | Keep enough thread engaged |
| Wire rope clip | Forms an eye at the rope end | The saddle goes on the live end |
Choosing the material
AISI 316 stainless for marine, pool and outdoor use; galvanized fittings are an economical choice for general and indoor work. All fittings must match the rope diameter.
Lifting applications
For lifting and carrying people, only certified fittings marked with a working load limit (WLL) may be used. Describe your application and we will choose the right set from our rigging hardware together.
