In this video, Mark Donovan shows us how to mount a mirror on a door. First, take the mirror and position it the height you want it located. Then, mark the top with a pencil and make sure the mirror lines up with lines on the door and it's in the center. Now, screw in the door attachments in the thickest part of the mirror. Attach the mirror and screw the screws so that the mirror is completely secure. Now, you can hammer in the screws to make sure they are completely attached to the door and mirror. Make sure you don't skip this step or the mirror can easily fall off of the door and cause injury.
