Attach the Lower Cabinets to One Another
The installers begin by turning each of the cabinets on its side and attaching a pine 1x4 board to the bottom of the framework (Image 1).
Note: A 1x4 board is actually 3/4" thick, so it will match the 3/4" thickness of the hardwood flooring to be installed later.
The first two cabinets are placed in position (Image 2) and clamped together using quick-release bar clamps (Image 3).
As with the upper cabinets, the cabinets are secured together using stainless steel screws. The installers first pre-drill pilot holes, then install the screws.
With the first two cabinets attached together, the installers secure them to the wall with screws (Image 4).
