Set of 4 Screws (Old Style) Extra Large
To determine the correct size door, simply measure the width (A) and height (B) of your pet.
(A) Measure the widest point of your pet's shoulder.
(B) Measure from the top of your pet's back (just behind their head) to the bottom of chest.
Pet door models have different size openings. Just make sure your new pet door's opening is both wider and taller than your pet's measurements to ensure they can comfortably pass through.

would be nice if frame replacement came as a whole kit instead of in pieces
I had to buy a replacement frame. No big deal, except you got a to buy it all in pieces. Screws or a separate. I missed one of the pieces and had to pay another shipping charge. I don't mind paying for any of this except the additional shipping charge for a little tiny piece. It would be nice if you could buy it as a kit.
