When I bought our house the floor vents weren't secured either. I had a friend with a drill put screws in each corner into the floor. I 'think' one at each end instead of all corners would work well. Oh, and don't use real long screws cause they take forever to get out when you want to clean the vents, but do make sure they are long enough that they hold well. Unless you look closely you won't see the screws in the edging of the vent covers. Hugs to all. tle Troy Lynn Eckart Ferret Family Services http://www-personal.ksu.edu/~sprite/ffs.html http://www.geocities.com/Petsburgh/Haven/5481/ Please sign up to support our charity http://www.iGive.com/html/ssi.cfm?cid=46&mid=58395 [Posted in FML issue 3555]
