This Hobart 140 to 80 Bowl Adapter ring for Hobart V1401 mixers this adapter ring allows you to use an 80 qt bowl on your 140qt machine. See pics for condition at the time on this listing this is 4 of 4 all 4 are in poor to good condition all will have at least 1 to 4 loose points on them that will make the bowl clank around during mixing.  But they will still work. That is why they are as cheap as they are.  In the near future I will be listings ones that are tight at all points. They will cost much more.  If you end up buying a ring elsewhere be sure to ask if the seller fit tested their ring and ask if it fits tight or loose.
