Searching for Paella storm door window parts

Hello!

Thanks for reaching out to us. I'm not sure I recognize what you have here. Would it be possible for us to see a clearer photo of this part? It would also be helpful if we could see it installed. 

Thank you! I am sorry to say that we don't sell a replacement or alternative for this part. Since this is a Pella brand door, your best bet may be to contact them directly. I apologize that we won't be able to assist with this repair but please let us know if you have any other hardware questions.
