I searched and searched for knobs to replace a couple that were broken on my Thermador dual fuel slide in stove - it is 15 years old and still works well but the knobs started breaking. Thermador/Bosch do not make the replacement knobs. I read a review of these knobs from someone who sounded like they had similar problem. The knobs are smaller than my original but they fit and they work great! Phew! Glad I got that solved.
