I don’t know anything about this, these were left over by a tenant. The large wheel says Flo-pac on it. I’m showing the top and underside view of it. It’s roughly a 19 wheel. The other wheel is a little under 8 which is the part that fits on the machine. The part that the pad goes on is larger, just guessing 10 wide. Plus you get all the pads shown.
