Need to know how to measure ot

I'm sorry, I'm afraid I don't know what it is you're asking. Can you kindly specify what information you'd like from us?

If you just want to identify the roller, it looks like it could be a match for either our 23-025 or 23-024, depending on dimensions. Note that the size of the teeth shouldn't be relevant. They're only meant to give you a little grip when you adjust the roller position.
