Hi @yinzermama
These are notoriously impossible to insert, and if the tool slips off or too much pressure is applied the screen will crack. My process is to shave down the these areas of the grills so they can slide in easily:

A Dremel tool is perfect for this. Then I’ll apply the tiniest amount of glue to these areas of the grill and hold it in the screen until it dries. This should hold for a long time and cause no problems for the screen.
