It's a tool that has been around awhile.  I had other priorities so it wasn't until recently that I picked one up.  Wish I had made it a priority sooner. 

Very well made of heavy aluminum extrusion.  It's modular and completely adjustable.  Once you understand it, setup takes around a minute.  Changing between common door sizes with the standard spreaders takes around a minute as well.  It comes with extensions for door widths up to 72" that take a bit longer to swap out and install.

A video from the company.   
Their install time once setup is accurate.

In use it performs as advertised.  The "shims" are blocks 1" x 3 1/4"( for a 4 9/16" jamb) that get hot glued inside the template pockets.  You trim the blocks down with a router.  The blocks end up level and square to the wall the jig is referenced off of.  With accurate setup of the jig and an accurate depth setting on the router you can size down both the hinge and strike side of the RO to perfectly accept the jamb.  The jamb slides into the opening with no resistance, but no side play, and will be plumb and square to the wall.  Makes casing install a snap.

I've run it on a few openings and so for I'm impressed.  The pics are from a reno with some pretty funky framing.  Kinda like trying to trim an Escher.  Pic one shows blocks glued in. Pic 2 is of a couple of the "shims" trimmed down to square and plumb the opening.  That RO had a nasty twist to it. The installed jamb didn't.   Pic 3 is a pocket door in a 2x6 wall I ran it on just to try it.  Ran the blocks solid over the split studs and once routed the centers over the door pocket were cut out with a hand saw.  The split jamb installed dead square, plumb and in line with each other.

I've installed a couple thousand doors shimmed with conventional methods.  For a one off I will likely continue to use them.  For multiples this is much easier and lends itself better to production/ assembly line type install methods which cut down time without compromising quality.  Just passing on the tip.  Some may find it useful.

Justin how well does it work with wider jambs? Lots of 2x6 construction with interior sheer and other fun things where I am.

$535 USD.

Seeing that I am now doing my pre-hungs with a cordless nailer, it more or less loses me with the hot glue gun and the router.

I'll have to think long and hard about this one.

Definitely a production tool.  Thanks for sharing. 

I remember when I was around 14 and on a new house build, my dad would hang 2 doors a day as he hung the jamb first and then machined the door to fit the jamb opening.  Never made sense to me when I started hanging doors, I made the jamb fit the door and could hang quite a few more doors in a day.  When I was 18 I trimmed condos one whole summer and started doing it in my sleep and waking up tired, I was glad when that job was over.  If you haven't guessed by now, my Dad was a contractor.  I got to spend a lot of time with my father, I guess I was lucky as not too many sons can say that today.  They don't know their creators.  Sometimes I can still smell the old port tobacco he smoked in his pipe and when "Burgers and Fries (and cherry pies)" comes on the radio it takes me back to my teens and heading to the job in the morning with my dad in the Chevy van.
