Thanks for posting. I am afraid the 81-156 only comes with 1-1/4" wheels. I believe a version with 1-1/2" diameter wheels was made at one time, but it was discontinued long ago. That said, you should be able to adjust the roller to make up a diameter difference of 1/4". Therefore the 81-156 remains your best bet for a replacement. Let me know if you have any questions. |
