If the wrench would tighten it enough to hold in reverse, I would make a
wrench. But if it won't, I'm going to return it & I don't want to waste
the time making the wrench. And probably marring the sleeve while using
it.

I emailed ENCO support & got the answer that "The spanner wrench would
lock it." $10.45 + shipping. I'll make my own - that'll be faster as
well as cheaper.
