How to Hang Kitchen Cabinets

With one or two helpers, lift the upper cabinet assembly into the corner and rest it on the cleat. As a helper steadies the assembly, check the cabinet face with a level to see if it's plumb. If it is, drive four 2½-inch deck screws (with washers) through the back of the cabinet, top and bottom, and into the studs. If it's not, slip shims between the cabinet back and the wall at the stud locations. (To shim out the bottom, remove the cleat.) When the cabinet is plumb, screw it through the shims to the studs. Lift the remaining cabinets onto the cleat, align their faces flush with those already installed, and clamp and screw the edges together (see STEP 3). Shim cabinets as necessary, then fasten them to the studs through the shims with the 2½-inch deck screws and washers. Close any gap between the wall and the end cabinet by scribing its stile or back edge, or by covering the gap with trim.
