It is important to note that the size range for the stile of the cabinet is 1.5 to 2 inches...the stiles (vertical frame piece) on my cabinets were slightly under 1.5, so I had to use shims with these clamps, which is a bit of a pain. Nonetheless, they do a great job of drawing the cabinet frames completely tight, while allowing you to make slight adjustments towards and away from the wall, so that the alignment is perfect...and then allow you to drill and insert trim-head screws to keep that perfect alignment.
