Need help identifying

Hi there! Thank you for reaching out to us. We don't sell a replacement for the weatherstripping shown here, unfortunately. I am very sorry that we won't be able to assist with this repair but please let us know if you have any other hardware questions. 

It appears to be a foam-type weatherstripping but I'm afraid we don't know who may carry it. Apologies again we couldn't be of more help and good luck with the repair.
