This is the rotating glass tray only. 16" diameter. The microwave failed, but the tray is in perfect condition as a replacement or spare if you want it. Microwave trays vary significantly, so it may not replace a different 16" tray. This one came from a Kenmore microwave model 721.66462500 manufactured in December, 2005. Again, it is in perfect condition. You are welcome to have it to try in your microwave.
