Patio door corner and roller

A quick learner from USA says:
What can I replace this with? I'm looking for something with a better quality. I'm not happy with the adjustments on this one. I was looking at 84-011 and 84-026, but not sure of the quality. Any suggestions?

Thanks for reaching out! Given the design and the measurements shown, I believe the roller you may need is our 84-026. Look over the dimensions and carefully compare them to your roller. Let me know if they differ at all.
