Designing a large-ish upper cabinet that will be open on the front. It butts against the ceiling and has to scribed around something on the side that prevents using a french cleat. I'd like to avoid screws through the back. Probably not possible, but anything I haven't thought of?
The back would be beadboard ply. I'm showing it flush but I can put cleats behind, just can't do a french cleat because i can't lift the cabinet up and drop it the 1" or so down.
