Maybe I should have added not to use the adhesive they suggest. From my source basically you use a reverse rivet to hold them in. Think about the underside of your cars hood. The attachment device uses extremely strong adhesive to stick to the inner box. Looks like a short upside down nail. Stick the sharp point through the insulation, then cap with a inch or so diameter cap.
