The Microplane Grater Attachment Food Guard slips on to the rail of the Gourmet Series Paddle Graters (except the Ultra Coarse Grater). Drop smaller foods, like garlic, ginger, chocolate chips, nuts, and small veggies into the hopper, push down on the plunger and grate! This accessory helps to easily grate these foods without putting your fingers in the way of the ultra-sharp blades.
