Every house we have lived in I have installed a pot rack over the kitchen sink. I've always used these brackets:

Our new house has the wall cabinets installed within 1" of the windows, 20230318_195633.jpg thus no room to mount the brackets to the window crips (or jacks).

So I'm thinking along the lines of something like this 2023-03-21_19h11_27.jpg (no snickering at my sketchup skills) that can be fastened to the header. I'm not comfortable mounting the rack right to the sides of the cabinets for 2 reasons: they are middlin cabinets, and I didn't install them. Perhaps bracket is made from aluminum? Or painted steel? Can't imagine making them from wood and having them hold up, but maybe I'm mistaken. Any suggestions or ideas are welcome.
