Work your way counter-clockwise around the perimeter of the iMac, adding three more adhesive strips in the same manner:

Strip 23 on the top right

Strip 22 on the top left

Strip 16 on the vertical left

These three strips have a hole at each end—always use the smaller hole for alignment for more precise placement.

On the iMac Intel 27" Retina 5K Display, the top-right strip's blue tabs will not line up with the top antenna in the same way as the non-5K model. This is perfectly acceptable and won't impact the performance of the strips or antenna.
