Looking for spare part

Thanks for reaching out to us. This roller reminds me of the 23-027. I recommend you look over the specifications and compare them with yours to confirm they match what you're looking for. You'll also want to pay close attention to the tabs on the back and sides as shown below in the second photo to ensure they match yours too.

We also have a similar roller, the 23-093. This has a different back tab than the 23-027.
