A shackle bow comprises a generally U-shaped body having a first end, a second end and aligned openings defined in the first and second ends. The body has a load bearing portion positioned between the first and second ends. The load bearing portion has a cross section comprising a bearing surface that curves through more than 180 degrees and an intersecting channel-shaped supporting surface. The channel-shaped supporting surface comprises opposing channel side portions extending from opposite sides of a channel base surface and a series of spaced apart ribs connecting the opposing channel side portions to each other.
