Replacement weatherstripping for vinyl windows

Hello there. 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. Dimensions of the end profile would also be most helpful. From there we'll do our best to find what you need. 

Thanks for the photos. I believe our 58-002 is our best match for this wool pile; just look over the dimensions below to confirm. Now, that center vinyl strips is known as a "fin seal." Some designs feature this fin seal, while others do not. Although the 58-002 lacks this center fin, I don't think it would be much of an issue for you application.
