We painted my son's bedroom, took down the ceiling ac vent covers. When we went to put them back, the holes were stripped and we can not get the vent to stay. I tried a longer screw, however, there is not much room to screw into. I can not get a molly bolt, or a plastic cover type fastner in there being as the hole is huge now, as well as there is not much space between the sheet rock and a hard surface, I assume it is the metal air duct. I have tried everything! At my wits end here! Any suggestions on how to make the vent stay. Is there a spring style vent cover? I looked at Lowes.com and do not see one.
Thanks in advance
