As other reviewers have noted, the factory holes did not match my old PetSafe door insert. However, it was very easy to mark and drill 2 holes in the flap to match our door frame. This damper seems to be of better quality than the one in the door when I bought it used. I don't think the valve I took out was original as there were other holes in it so I can't tell how it compares to the original valve. Definitely worth the price.
