Each adhesive strip has a flexible liner on the back, and a stiff liner with hole cutouts on the front. As you orient your adhesives, make sure the stiff liners with holes face upward.

Before applying your new adhesives, lay them out over your screen to find their proper orientation:

The long piece with curved ends is for the top edge.

The other long piece is for the bottom edge.

The short piece with a notch cutout is for the edge with the screen cable. The notch should be closest to the top edge.

The other short piece is for the edge opposite the screen cable.
