Using two of the included 3M command strips, apply each tape piece to the the back of the mounting bracket as shown in the video below. (Knocki includes a backup pair).
The side of tape with RED should contact the plastic bracket, and the side of the tape with BLACK should contact the mounting surface. Replacement 3M command strips (small) are available on Amazon.
