LOML wants six of these shelves installed in her office. Flush mounting is an important feature.

The Pottery Barn product comes with an aluminum french cleat assembly. I've found similar assys at HD, but they're ~$10 each! They look sort of like this.

So far I've found some other choices, each of which has some limitation or complication. In addition to the hardware shown below, there is also a classic french cleat. How would you engineer the mounting of this kind of shelf?
