I went and watched this 1 min video clip about hanging cabinets:
It seems to say to just screw my cabinets into the wall (where the studs are) through the back of the cabinet.
The cabinets I am going to buy from home depot don't really have a solid backing (not sure what it is, but it is some kind of thin composite material.) If I screw through that I am fairly sure that my cabinets will rip off the wall in fairly short order.
What is the procedure for getting those to stay on the wall? I would rather not put a second layer of wood inside my cabinet, but that is all I can think of now (or use a really really big washer :)
I would welcome any ideas.
