Hello! This door looks like it could be the old Pella Proline series. If so, our 82-247 is commonly used on this application. This may be what you want, but I highly recommend removing the original to verify that the size and design matches our product.
That's unfortunately not a series I'm familiar with, and my records don't list whether the hardware for that door is meaningfully different. At this stage, the only way to verify for sure whether the 82-247 will work for you is to remove the original. If your lock is different, then we would need to see a picture of it removed anyway so that we can research a better match. Your next step will have to be to remove the old lock either way.
If it does end up being different, you can submit a photo of here and I would be happy to look into an alternative solution.
