I welded this double hook from two Harbor Freight grab hooks and a
1/4" steel plate. The purpose of it is to let me use arbitrary lengths
of chain, single and two ends, when lifting stuff, as well as grab to
access lifting eyes with just a piece of chain (see last
picture). Welding was done with 1/8" E7018 electrodes.

While you will no doubt get lots of advice on welding and redoing the heat
treatment of the hooks (if HF hooks are in fact heat treated), don't forget to
proof test this to four times the intended max load.
