This was a great purchase. I’m using it on an interior door to my basement since there was a rather large gap from the bottom of the interior door. I decided to mount it on the inside of the door where it would actually be visible from my first floor interior. It actually makes the door, which is painted white, look as though it has some ‘fancy’ trim on the bottom! I never expected to have a door sweep become a ‘fashion statement’, but that’s what happened. It was very easy to install and it stayed put pretty much immediately! All good!
