Mayfair Patio Sliding Glass Door

We don't have a version of this roller that matches those dimensions, unfortunately. The 81-001 remains the best option in our inventory. 

I would triple check the width just to be sure yours isn't perhaps closer to 5/8". You said it was between those two measurements and I'm hoping it leans that way a little more than the other.

As for the wheel diameter, you can usually get away with a difference in size if you adjust the wheel to make up for it. If that doesn't work, we do sell replacement wheel kits separately. See our 81-272, for instance.
