Patio door roller

I'm sorry to say I don't recognize this particular style. Would it be possible to see a photo of the roller this wheel attaches to? If we can't supply this exact wheel, maybe we can find something that would still work in the same application, even with some alterations. Seeing the roller assembly in full would narrow down the list of possibilities considerably. Thanks!

Thanks! This is a huge help. Your roller assembly strongly resembles our 81-019. I think this may be what you need, though unfortunately the wheel is not sold by itself. Would replacing the entire assembly be an option?

You can review its specs below to verify that they are a match.
