Step 1 (starting with the top image): Mark the location where the clip for the shelf will go on your wall. Predrill a 1/8" hole straight into the corner where the two walls meet (corners almost always have studs, if not, use a 3/16"x3" toggle bolt). Hold the clip in placve and screw in the provided phillips screw until tight.

Step 2: Peel the backing off the mounting tape that is attached to the clip as shown.

Step 3: Put the glass all the way back into the slot while tilting the front upwards. Push the glass downward into place so that the mounting tape sticks to the top of the glass.

The installed Corner Shelf Clip should look like the bottom-most picture above.
