This product is a practical replacement pack containing two (2) robust control knobs specifically designed for commercial, gas-operated egg bread/burger maker machines that produce 5 pieces simultaneously. These machines are essential in quick-service restaurants, cafes, and catering operations for efficiently preparing uniformly shaped egg patties or burger bun equivalents. The included knobs are vital for precisely controlling the gas flow and, consequently, the heat to the individual cooking sections, ensuring consistent and perfectly cooked egg bread/burger patties.
