A:Answer Hi DoctorEd- Yes, all 30" over-the-range microwaves are approximately the same width, and are designed to fit into a 30" wide cabinet opening. Each microwave comes with the mounting hardware (mounting bracket, screws, exhaust adapter), top and rear templates, and installation instructions needed to make installation a simple process. This makes choosing a replacement microwave easy.
