Frequently Asked Questions

Bolt type shackles are typically selected for connections under sustained vibration, side-loading, or cyclic loading, the bolt-nut-cotter assembly prevents the pin from backing out. Screw pin shackles are the match for routine rigging where the connection is made and broken frequently.
Anchor (bow) shackles accept multi-leg sling connections in the rounded bow and handle side-loading per manufacturer chart. Dee shackles are the match for straight-line pulls where side-loading is not a factor.
