This is all the info I have. I asked them to send me sizes but they can not at this time. I was hoping I can get it Identified before I head 2 hours away

Thanks for posting. I'm afraid this roller has been discontinued and no longer available. Can you get away with just replacing the wheels? If so, take a look at our 81-228 Nylon Concave Wheel, or the 81-226 and 81-310 Repair Kits. If the housing itself is damaged, I'm afraid we do not have a replacement. Sorry for the inconvenience.
