Hey there,
Thanks for writing in! Would you possibly have an undamaged latch? I am not confident that we have a replacement solution but I am happy to take a look into this for you. Although, unfortunately, it is difficult to confirm the replacement based on the photos here.
Please let me know if you have any questions.
Okay, I understand. To be honest in all my years of repairing and manufacturing storm windows, I have never come across a storm latch like the one in your photos. Since it is hard to get accurate dimensions it will be difficult to confirm exactly what you need, but take a look at our 91-070 All Weather Style Latch Pair and our 91-090 MO-CO Replacement Latch Pair, to start. See if either these will fit your bottom lift rail.
Also, see if you can retro fit the "tip" to fit your storm window track.
Our entire selection of storm door latches can be viewed, here.
