being that the new vents have 3 little protrusion tabs....in order to help secure them....I'm willing to bet that some of the 250 of these that I will be installing, will not, in fact stay put with just the 3 tabs. (I've done this job before, on a different house) Therefore, I would like to help those tabs with some type of glue, epoxy, or whatever would work best.
P.S. The new vents come with a (much) smaller wire mesh, that should stop the wasp problem....I hope.
Also, I'm not sure why I would ever need to replace these once they are installed......(unless, of course the adhesive fails at some future date...?)
if they last 10 years give or take....that will be fine with me.
