How are people checking frameless cabinets for square on installs? I've always done my best to get them plumb and level, put the doors on, then give them a final tweak, but then the doors are in the way for installing molding etc. Measuring the diagonal isn't really an option in most cases. Should I use a framing square? I realize that with a square cabinet, perfectly plumb and level should do it, but sometimes I rely a little too much on hinge adjustments to align doors.
From contributor F:
I build my base cabinets with a separate ladder frame. I fasten the whole run together before fastening to the wall. With upper cabinets I use deadmen to support them while I do the same, attach them all together, then shim, level, and fasten to the wall. Any adjustments I can make with the hinges. Another thing that I find helps me is pre-assembling the cabinets in the shop. By doing this I can find any potential problems ahead of time and installation is even faster.
