Rubber Seal
I'm sorry to say that we don't sell a weatherstripping type that matches what you show here. Admittedly, I'm not sure I recognize this style. Would it be possible to see an undamaged version of the end profile? Can you also clarify which portion of the end profile installs in the window track?
The video below will go into more detail as to what I mean. I can't guarantee that we will be able to find you a match with this information, but I will try my best.
That is a huge help, thank you. Unfortunately it does confirm that we don't sell anything that can replace this. Having the bulb end be the insert is a very odd design; almost all of our seals use a flat kerf of some kind.
I am very sorry for the inconvenience. This won't be something that we can supply.
That's very considerate of you, thanks! We appreciate it.
You have a great day as well. We're always happy to help with any future window & door projects you may have.
