Bypass door and adjustable roller

Thanks for reaching out to us! Your roller reminds me of the 23-081 or 23-086. The difference between them is the wheel: the 23-081 has a convex wheel and the 23-086 has a concave wheel. Yours appears to be a bit beat up so I can't confirm which of these you may have. Would it be possible to see an undamaged version of this wheel? If not, may I see a photo of the bottom track?

Great, you'd want the 23-086 since that's the case. Review the dimensions and see how they compare with yours.
