Cross posted on appliances but thought I'd put it here, too, in case....

I've seen quite a few manufacturers of wood hoods mention a 'french cleat' hanging system which is a metal plate screwed to the wall with brackets that are attached to the metal plate. The insert is screwed to and hangs under the brackets. Then the wood decorative hood can be mounted over the whole thing.

Problem is I cannot locate a source for the french cleat system for the inserts. Anyone know of where I can find such a thing?

The link below is a PDF of the cleat system and hanging instructions, if this would help anyone help me find it.
