Includes: (1) Grinder Plate Size #22 (5/16" holes) - Hub Style (non-reversible) Dimensions: Plate Diameter: 3 1/4" Center Mount Hole: 7/16" Holes Diameter: 5/16" (7.94 mm) IMPORTANT - ALWAYS REPLACE KNIFE AND PLATE TOGETHER AS A MATCHED SET Always use the same knife and plate together. If one has gradually worn away from perfectly flat, the other will have worn with it. As a result they may still be used together, however, if one is matched with a different item which is perfectly flat, the set will certainly not turn out a good product. In addition, such practice will probably break the new item.
