ABSTRACT:
A grab hook for shortening a chain or for forming a sling therein comprises a shank portion with an upper suspension end, a point portion and an intermediate bridge portion. Shank portion and point portion are separated by an arcuate chain link introduction opening having substantially parallel edges and ending at the bridge portion. To make the hook suitable for short link chains as well as for long link chains the bridge portion is laterally displaced with respect to the suspension end, and on one side of the hook the edges of the introduction opening widen into arcuate recesses in the shank portion and the point portion, respectively. These recesses end in shelves which are located above the top side of the bridge portion and are adapted to support a chain link.
