Need to replace IPD Peachtree Patio Nylon Sliding Screen Door Roller 1-1/2 in

Thank you for reaching out to us! The hardware in your pictures is a discontinued roller that's no longer made, unfortunately. I'm afraid we don't have anything that will replace it. The manufacturer is Peachtree and much of their hardware has been discontinued for some time. Finding a dealer in your area familiar with Peachtree parts may be your best bet. I apologize we cannot be of more help.
