replacement parts for closet glass door

Hello,

I don't recognize this roller at first glance but I do know that Charmac has been out of business for quite some time. I'm going to have one of our senior experts take a look and see if they could recommend replacement parts for you. We'll reach out as soon as more information is available. Thank you!

Unfortunately, we do not carry a replacement for the top guide in your photos. As for the roller, we'd like to see it removed from the door to confirm if we can supply a replacement. Thank you!
