Exactly what you need when your old one starts falling apart!
This perfect replaces the old under door weatherstripping on my exterior front door that started falling apart. Installation was fairly easy, just take the door off the hinges, lean on it's side, use a flat head screwdriver to pry the old one off, and position, tap/lightly hammer the new one in. This was exactly the same length as the one it replaced and I've taken pictures of the old one to show the length. I had to adjust the frame sill up slightly to seal it against the door but most modern doors have that feature (the 4 large Phillips screws on the sill used to adjust height). Definitely will buy again if this one lasts at least as long as my last one did! (7 years of light usage).
