The drawing shows the jacks I use to install upper kitchen cabinets by myself. The jacks have a 2×2 frame covered with 1/4-in. plywood, and they’re braced with 2×3 legs. I line the backs and tops of the jacks with strips of carpet to keep them from scratching the walls, and I’ve got rubber feet on the legs to keep them from slipping as I adjust the height of the cabinets.
To use the jacks, I mark a level line on the wall to show the bottom of the cabinet. Then I place the jacks about 6 in. inside each end of the cabinet, and I set the cabinet on the jacks. Moving the legs in or out adjusts the height of the cabinet. When I’ve got it right, I fasten the cabinet to the wall through predrilled holes in the cabinet hang-rail.
