Sliding glass door roller

Thank you for reaching out to us. We don't sell this exact roller, I'm afraid. However, we'd be happy to see if we can track something down. Can you show us photos of the top of the roller as well as the back end? We would also like you to write out the height and width of the roller housing along with the diameter of the wheel. It would also be helpful if you know the brand name of your door.

There's a chance we may not have a match but we will do our best to find an equivalent size. 

Great! We will be here to help whenever you can get that for us.
