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. Screw pin shackles are easily manipulated. They are typically suitable for non-permanent applications and one-off installations, when there is no tendency for the pin to unscrew and the shackle can be observed under operation.
