What are the types of shackles that you can choose? Anchor (bow type) and chain ("D" type) shackles are used with screw or round pins. - When selecting the right shackle, refer to manufacturers' tables for the safe working loads of the shackles.
- Shackles are sized according to the diameter of the bow section rather than the pin size. Never use a shackle if the distance between the eyes is greater than listed in the manufacturers' tables.

How should you inspect shackles? - All pins must be straight and all screw pins must be completely seated. Cotter pins must be used with all round pin shackles.
- Replace shackles worn in the crown or the pin by more than 10% of the original diameter.

What should you avoid when using shackles? - Do not replace the shackle pin with a bolt. A load will bend the bolt.
| 
| - Do not allow a shackle to be pulled at an angle. The legs will open. Pack the pin with washers to center the shackle.
| 
| - Do not use screw pin shackles if the pin can roll and unscrew. If the load shifts, the sling will unscrew the shackle pin.
