Gunner noticed:
Several riggers around here use a gizmo that slips over the tounge on
Simplex jacks and allows you to go under the edge of a machine and get
it up far enough to stick a 2x4 or another Simplex jack under it.

Clever idea, I've not seen one of those. If this gizmo extends and
lowers the reach of the jack do they block between the jack and the
machine to keep the jack from tipping forward or have they figured out
something better? Seems like this extension gizmo might be a good
add-on product for a jack. Bet McMasters and others would be
interested.
