The track is fine, but I can't find the rollers that fit.

I'm afraid that we do not have replacement rollers for cats. They should be able to move on their own, curiosity permitting.

In all seriousness, it's hard to tell what rollers would work for this track without more information. Can you tell me what this is used for?

Oh, I see. I didn't know you still had the old wheel on hand! That will help a lot. Can you tell me its diameter and thickness? Could I also see it from a few more angles? It looks like something is broken off on the back of the wheel, but I can't quite tell.

The roller is 1" diameter roughly a 1/4" thick. The center is 5/8 of an inch and this is what's giving me trouble. Nothing I see is this small.

You should consider one of our shower door rollers. Look at our 10-101 7/8" oval roller or 10-109 7/8" flat roller. You will also need something like our 33-087 screw to fasten it to your door.
