Also, this principal does not rely on gluing horizontal supports to the back and front center supports because what do you glue to when you have a mirrored back and a solid glass front door with horizontal supports?
Umm. . .the mirror and the glass?? Which is what I planned to do until I found you had a better idea. This also alleviates my having a 7' cabinet lying face down and then lying back down on the floor while I wait for the caulk to cure.
