Re: hanging upper cabinets without studs
Studs are generally 16" on center, so it's usually not too difficult to snag at least two studs with a single cabinet. If you have multiple cabinets, then connecting the cabinets together as well as attaching them to the wall makes them all share the load and attachment points.
If in fact you can only attach to a single stud, then the weight that the cabinet can handle will be seriously compromised.
