Neat idea, but it is not apparent what connects second clamp to the jack-screw.

I will field this, the jack screw is connected via a long nut welded to the tab that the second clamp is clamped on the nut is inside of the long cylinder and has a slot the tab can travel in. Think of the function of screw in a cross slide or compound unit

I see that, except it is not visible, or connects so quickly. It looks to just rest in the saddle, unable to transmit force of screw. I'm googling up supplier/ manufacturer.
It's good to sell features with visual demonstrations, the unclear parts might be the root of patent infringements, lol.
The only big (outside Ridgid) pipe-fitter gear company I know is Mathey-Dearman, so this'll be entertaining.

Ah hell;
Must have blinked at same moment of each viewing.........the second clamp ISN"T a saddle, it's ATTACHED to the jackscrew tube.
Bingo!
But now want to google even more......
