Mahlkonig EK43 Shear Plate.
This is the OEM replacement shear plate from Mahlkonig for grinders with black pre-breakers. This version is made from a solid piece of brass providing a long lasting and reliable service life.
This specific version will fit all EK43S models, as well as any 2nd generation EK43 grinders that have round, stainless on/off buttons and a black pre-breaker.
The shear plate is designed to break in the event of a clog in the grind chamber. The plate breaking prevents major damage to the grinder motor- a very costly repair.
The black pre-breaker was used in second gen EK43s that have the round, stainless on/off buttons. If your pre-breaker is silver in color, you need the gen one version, found here.
