This is a bracket used to hang a piece of pegboard from the top of a cabinet with crown molding that would make it hard to use a bracket with a regular shape to hang pegboard.

It works for cabinets with this common shape of crown molding. There are small standoffs to keep the board lying flat against the side of the cabinet.

I wrote a blog post with some more details. You can access the parametric designs for the hanger and standoff from my pegboard accessories Onshape Project. Please feel free to fork them and modify the sketches to work with your cabinet.
