Thanks for reaching out to us. It's tough to get accurate dimensions from photos, unfortunately. The pile weatherstripping we've related for you on this page has a fin seal but the dimensions might be off. Take a look and see how they compare with yours.

If you're interested in samples, just let me know. Note, we offer up to (5) and you'd have to pay for shipping.
