- Match the Working Load Limit. Pick a capacity at or above your maximum applied load. Never exceed the listed WLL.
- Confirm size and fit. Check bow clearance and pin diameter against your sling, chain, or hardware.
- Consider the environment. Type 316 stainless is preferred for saltwater, coastal, and chemical exposure.
- Plan for inspection. Replace if you find thread damage, distortion, or excessive wear.
