This Estella foot is a direct replacement for the ones that came standard on your Estella SL series meat slicer. It is compatible with SLM12, SLM13, SLA13, and SLA13S meat slicers. This foot is a replacement for the feet located on the back of the slicer behind the cutting blade. It helps keep your slicer stable and securely in place, ensuring it does not slip or slide during use. If your original foot is worn out or broken, replace it promptly to continue proper operation of your meat slicer.
