Unknown Patio Door roller

The patio door wheel roller just came apart. The door is a black aluminum sliding door. Not sure about the make.

I don't see anything which looks exactly like this. Are there any universal fits that I can use?

Am I limited to a single-wheel roller or can this be upgraded to double wheels?

Hello! Thanks for reaching out to us. There is no such thing as a universal roller of any type, unfortunately, but the good news is that our 84-021 looks like a dead ringer for your original. Look it over and see what you think.

To my knowledge, no double-wheel version of this roller was ever made.
