The one in mine resembles closet bars. It's definately NOT structural (mine moves all over the place, I can even pull it down a few inches). It's there to hide/protect the wiring that runs from the breaker box (in mine) up to the lighting
installed in the upper cabinets. It only needs to be replaced if you're running wiring, and even then you've got a world of options of how to do that (PVC, track stuck to the wall etc).
