Sliding Patio Door Weatherstripping.

Since your part is still installed, it makes it difficult to order a definitive recommendation. We would need to see a piece of it removed from the window and from an end profile in order for us to offer some suggestions. If you could do that for us and include detailed, that would be very helpful. 

In the meantime, you can go through our selection of wool pile to see if you are able to find what you need.
