My name is Dimitri,
See my pictures of weather stripping in my home.
Looks like you carry two out the three but can but can’t find the third one. Looks white one the picture and it goes in the middle where the two windows meet.

Hello Dimitri. I believe you may be able to use our 58-053 kerf mount bubble seal for your window interlock between the two sashes. Take a look and let us know your thoughts.
