19.5.2 Choice of Body Shape

Select the shackle body shape based on intended use, using the smallest jaw opening that allows adequate connection articulation. Dee shackles are, in general, used to join two pieces of lifting equipment. Bow shackles are, in general, used where more than one attachment is to be made to the body, or to allow freedom of movement in the plane of the bow. (SeeFigure 19.5.2-1 )

The necessity for the eye of a shackle to pass through another fitting may have to be considered. Where a shackle does not have to be dismantled, or where it is required to remain captive, it may be permanently attached by forming a link or thimble round the shackle body. (See Figure 19.5.2-2 )
