window weatherstripping

Thanks for contacting us. This looks like snap in glazing, not weatherstripping. These are used to hold the glass in the frame of the window. 

Now, we don't have a type of glazing that matches your example exactly, but we do have the 55-029. This has 1/2" long "legs" and looks very similar to your style. Could you possibly get this to work in your window? If you want, you can order a sample of it here to be 100% sure. Let me know what you think!
