I was a little skeptical if these would really work. I have a very wide flap door that opens to the ceiling. This was an easy install and work better than expected. To open the door there is just a little resistance and then it opens flush with the ceiling. To close was even a bigger surprise. It starts closing and you should expect a big bang. NO!! It slows down and quietly closed. A real bonus I returned the dampers I bought because they weren't required.
