Roller Product for sgd-r20 sgd-r25 series 800-3100

Hello, Gilbert. According to this sticker, you have a door made by Anlin Industries. The bad news is that I've never heard of this company before and I don't know what roller is used.

Truth be told, even being familiar with the company who made the door is rarely enough to ID a roller. Companies I'm more than well acquainted with will use all kinds of different parts. The only way to reliably identify a roller is to see the original, which will require you to remove the door first. I know that's probably more work than you wanted to put into this project, but it's usually always necessary.

Once the roller is out, I will need to see it from the back end, top, and sides. Written dimensions will also be necessary. After I have that data, I will check our inventory to see if we have a match.

You may find the video below to be helpful. This is a general guide for how to remove most types of patio glass doors. As mentioned before, I'm not familiar with the Anlin brand so I'm not 100% sure how relevant this is for your project, but I don't see anything particularly weird about your door. I'm hoping this process will work fine.

Thank you, and you as well! We're here to help with any questions you may have.
