You'd gotta be kidding me, right? I see that right away, but worked as manufacture tech, that is for tech bench having various test leads. You attach level, up around five feet off floor.
See also, there is (second photo I'm talking about), the fingers each has a little uplift in end, again for slide your clip leads or scope probe w leads.
OR, was that pict, just someone posted as nearly same? In which case, sorry I wrong there.
Thanks
