Thanks for writing in. Does the wheel in your roller have a flat edge? If so, I believe you might need our 81-078. Review the dimensions below to see if this matches what you have. One concern of mine is that the 81-078 has nubs on the side, whereas from what I can see your roller lacks them. Still, this may be our closest match to what you have. Take a look, review the dimensions, and let me know if you think this could work for you.
