Low sash bottom seal

Hello there! Thank you for reaching out to us. I'm afraid it's hard to get a good look at your seal from these photos. Could you remove an undamaged sample of this seal and show us a clear photo of the end profile? In the meantime, feel free to browse our section of weatherstripping here. 

Yes! Thanks for getting that for us. I'm sorry to say that we don't sell anything like what you have here. We aren't sure who may have a replacement or alternative other than the original manufacturer or supplier of the window, whoever they may be. I truly apologize that we cannot assist with this repair; please let us know if you have any other hardware questions.
