Replacement weatherstripping for vinyl windows

A handy person from Fredonia, NY says:
I'm trying to replace the weatherstripping for my vinyl double-hung windows.
the old strip measures 3/16 by 3/16 with a center vinyl strip (actually 2, side by side). Do you sell this type. If not, how important are the center vinyl strips? Can I substitute the 58-002 or the 58-127?

Good Afternoon,

Can you send us a photo or drawing of the profile of your existing weatherstripping? This would help us understand exactly what you are trying to replace.

The center vinyl strips are known as "fin seal." Although the 58-002 Wool Pile does not have a fin seal, I don't think it would be much of an issue for you application.
