Hey there, thanks for posting! Take a look at our 81-078. I am confident this is the replacement roller you'll need. To confirm, compare the dimensions below to you existing hardware. Let me know if they are not a match.

Hi Jasmine, We ordered these rollers, and they have just arrived. They are perfect except for the shape of the wheel. Could you suggest a similar roller with the proper shape of wheel? It rolls over a raised track. Please note shape of wheel in the Photos I sent.

My apologies. I missed that detail when I initially reviewed your hardware. Take a look at the 81-044, it is the same version of this roller but with a concave wheel.
