Shackles approved for lifting. Bow shackles are suitable for use when more than one attachment is to be made to the body (multi-leg systems), or to allow freedom of movement in the plane of the bow. Locking bolt shackles are recommended for long-term and permanent installations, or when there is a natural tendency for the pin to unscrew (rotate) in the application, or when the shackle cannot be observed under operation.
