[hitchup]

We have the 1- rack GE Micro/Convection. It has 4 clips to mount. I can use a 9 1/2" X 13" cookie sheet on it.

I've seen metal cabinet shelving that you might be able to use. It would need to sit outside of the turntable, unless it's removable. But you just never know you might stumble across one in a Kitchen Outlet store or Bed, Bath and Beyond or even at a Lowe's.
