Pamela B Santa Rosa , CA August 05, 2018 The plastic was broken off the screw holes I placed it on top of the microwave and screwed it on......After I had to go to the hardware store and get the 2 screws. It would have been much better if the 2 screws had come with it! 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
