Roller for this track

A home owner from California says:
Hi, I have a similar track need to be replaced. Is this track 23-272 fit the roller Cox 21-717? I attached both my current track and rollers pics. Please advise. Thanks!

As long as your roller has a concave wheel like our 23-070, the 23-272 track should be a suitable repalcement. Thanks for posting!
