This attachment is used but in good working condition. There are some scuffs and scratches on it from normal use. This would be a great item to speed up your food prep. This is for the Hobart #12 hub. There is a piece broken off of the feeder door hinge (see pictures) but it still functions as it should. This also comes with 2 shredder plates.
