The 40-197 is TOO BIG! One of my Larson Storm Door serial numbers is 34904031.411120914. When I enter serial # into input field on Larson website, get nothing. I have looked everywhere to no avail about these strike plates and we have just purchased and installed doors within last 3 years. Any help you can provide will be GREATLY appreciated!!
Thank you!

Can you show me a picture of your existing strike plate? Can you also give me your measurements? You can use the 40-197 as reference. That will help us find a better match for you.

Please see photo as requested. Also, the measurements are as follows:
7" from top to bottom
3/4" in width
top screw holes 9/16"
door latch holes 1 9/16"
Hope this information helps you find what I'm looking for and I truly appreciate you assisting me! I am noticing I am not the only one out there with this very problem. These are replacement doors from about 2-3 years ago as I mentioned, and they are no where near the quality as the last! Much more expensive to boot!!
Kind Regards...

Thanks for your patience in this matter. At this time the 40-197 is the only strike plate we carry in this style. It seems the only issue is that our hole spacing has 1/4" difference. Could you redrill one of the holes?
