Step 19: Hang the shelf.

Picture of Hang the shelf.
Finally I simply slid the shelf down onto the cleat which is attached to the wall. The only thing I plan to do differently in the future is to countersink the screw holes and plug them after the cleat is mounted.
I think you'll find that while there are a few extra steps to make this type of mount, it pays off when it comes time to hang the shelf.
