Set the pre-cut adhesive strip next to the rear cover so that it is properly oriented—the pull tabs should point to the bottom left corner of the cover.

Optionally, you can tape the pre-cut adhesive strip into position for easier application.

Lay the pre-cut adhesive strip over the rear cover, aligning it to the long edges.

Tape one long edge of the pre-cut adhesive strip to the rear cover, locking the alignment in place while allowing the strip to still swing.
