Rollers for patio doors

I'm afraid that I've never run into this roller before. I have come across the KILIAN branding before, but our records show that name to be associated with a bunch of different parts, and none of them match what I see in your photos.

Could there be more to this roller? I'm wondering if maybe this is just the inside portion of a complete roller assembly. I would check your door for an outer housing. If I'm right, seeing the whole assembly together would be a huge help.

Let me know whenever you get a chance!

Thank you! It's tough to tell while it's installed, but we'll do our best. Please give us a little time to look into this and I'll let you know as soon as we can.

Hey there, I think I can help. Take a look at our 81-281 roller. This has those same back tabs as yours, so I think it's worth looking at first. I'm not sure if you will be able to snap the wheel into your existing housing in the door. From what I can tell, you will need to remove the complete bottom rail off the door to access the mounting screw. Some doors are designed this way, which can be frustrating.
