I didn’t want my doors rubbing against my cabinet faceframes so I attached a strip of 1/4″ plywood at the top and bottom rails. There was a joist right above the front edge of these upper cabinets, so I butted a 2×4 up right against the front of the cabinets and drove 3″ screws in at an angle in order to secure it to the joist. The 2×4 is there to give me something to mount the rail onto, as I didn’t want to rely on anchor screws. While you could skip this step, I like to make sure everything is secured and built as safely and professionally as possible. It’s usually better to take the extra time/go through the extra step rather than regret being so hasty later on. Trust me–it usually comes back to bite you! Ah, the final and most important step in the process–installing the actual hardware! As I said before, I ultimately decided on using a premade slide.
