Hi there!

Take a look at our 81-167 roller. Review our dimensions and compare them to your current roller to see if this matches up for what you need.

Hello,

Your 81-167 rollers show as a discontinued product. Is there a replacement model available?

Thanks for reaching out to us. We don't have an alternative for this discontinued roller, unfortunately. If the housing is in good shape, we recommend you try and replace just the wheel. You can browse our Patio Glass Door Replacement Wheels & Axles section here. I am very sorry for the inconvenience.
