The microwave actually is recessed into the 4" deep wall. It's a SHARP over-counter microwave that hangs under a wall cabinet. The wall cabinets are the typical 12" depth. No, there is no handle on it. The door opens a full 90-degrees to the left. There is a filler along the left side to give it a little more room to swing. Of course, it eventually can bump the cherry cabinet. But you wouldn't typically need to open it beyond the 90 degrees.
