I'm not sure what weatherstripping Castle used. We will need you to remove a small and undamaged sample and show us a picture of the end profile. That will allow us to find a good match. The video below will clarify, though I need to stress that the sample has to be totally undamaged. If it's too deteriorated or if pieces of it have torn off, we won't be able to help. |
