WARNING

Improper use or care of shackles can result in bodily injury or property damage.

To avoid injury or damage, always observe the following when using alloy shackles:

Use only alloy chain and attachments for overhead lifting.
Do not exceed working load limit.
Do not shock or impact load.
Do not side load - center line of load must coincide with center line of shackle.
Do not replace pin with other than original equipment parts.
Inspect before use for wear, deformation and pin engagement.
