Rollers for a sliding door leading to the exterior

Thank you for reaching out to us. I'm afraid we can't ID your roller from these photos. The last one shows only the inner housing. There should be an outer housing to go with it, likely still in the door. We'll need to see a complete assembly removed from the door and put together to determine whether we have a comparable match. Written-out dimensions are also helpful. 

Unfortunately, this sticker doesn't help us ID your roller. We specifically need to see a complete roller assembly put together and removed from the door.
