rollers for sliding glass door
Hello!
Thanks for reaching out to us. I'm afraid we aren't able to offer insight without a photo of the roller in question. Furthermore, guardian isn't the manufacturer of the door. It only pertains to the glass in the door.
We'd be happy to look into this for you but seeing a complete and undamaged roller assembly removed from the door is the only way for us to do so.
Unforutnately, we do not carry a narrower version of the 81-020 roller. We'd be happy to look into this for you but, as Emily mentioned above, we would need to see photos of your original roller uninstalled to determine if we carry a closer match. If the dimensions do not match the parts you already tried, there are likely other subtle differences that are hard to differentiate.
