The tasks of hanging a heavy cabinet and a light one are not very different. The only complication in hanging a heavy cabinet arises when considering how to hold it in place while you fasten it to the wall. You can save your back, and that of the friend you were planning to ask to help you, by temporarily attaching a simple support on the wall and resting the cabinet on that. When the cabinet is hung, you can simply remove the support and patch a few holes.
Things You'll Need
- Stud finder
- Scrap two-by-four
- Phillips screw bit
- 1/4-inch drill bit
- Lag screws, 3 inches by 3/8 inch
- Socket wrench

Make a mark on the wall where the bottom of the cabinet will be. Take the doors off of the cabinet.
Use a stud finder to locate the wall studs. Alternatively, you can knock on the wall until you hear the solid sound of wood.
Set the two-by-four on the mark and, using the level to make sure it is horizontal, screw it into the wall studs with 3-inch screws. If these are sunk 1 to 1-1/4 inches into the studs, they will be literally strong enough to stand on and will easily support pretty much any cabinet. Ensuring that the two-by-four is level will save you the step of leveling the cabinet while you are holding it in place.
Lift the cabinet into place and set it on the two-by-four. Have a friend hold it while you drill 1/4-inch pilot holes through the structural frame inside the cabinet into the wall studs. Drill holes for as many lag screws as will hold the cabinet securely.
Use a socket wrench to screw lag screws into the holes, being sure that they sink well into the studs. They should sink about 1-1/4 inches, but no deeper, as you don't want to screw into any electrical wires that may be there.
Remove the two-by-four. Patch the screw holes with a little spackle or drywall joint compound. Touch up with paint, if desired.
