Looking for replacement rollers.

A home owner from Centerville, VA says:

I could not find any branding or identifying numbers or marks on any of the hardware pieces or on the door. The window did have the name Guardian etched into it with other information that appeared to pertain to the glass itself, I did include a picture of it.

Thanks for any help you can provide.
