Hi there!
Thanks for reaching out to us. I'm afraid we can't ID what you may have here from these photos. Can you remove an undamaged sample of the seal? We'd like to see a clear photo of the end profile.
That's understandable. However, that is the only way for us to confirm if we have a comparable match. I apologize for any inconvenience.
Unfortunately, the information etched on the glass is only relevant to the glass itself. It doesn't tell us the seal your door uses. Seeing the undamaged end profile of the seal is the only way we can help.
Certainly. I recommend you have a look at this section here. This should give you a better idea of the angle we're looking for.
I'm afraid we can only offer an educated guess which is the 58-181. You would ultimately have to remove a sample and compare the specifications to see if they match up.
