Set of 3 Screws (Old Style) for Large Size
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.

Fit perfect
First time that I had to replace the screws since I installed the assembly in 1997. Had to replace the other parts several times.

Best ever quick delivery
Finally a Company that has all the necessary items to the product you ordered. Other Companies I submitted it did not have all the parts in assembly. Thank you for having all items to assemble this product.
