The knobs are similar and work great, but they are not the same as factory Weber knobs. The Weber knobs are more detailed. They definitely do not completely match and stand out as different. Only need 1 knob, but ended using both to give a look of symmetry as one odd knob.............. looks odd.Look at your current knobs close and look at the listing picture close to make sure they are right for you. definitely different.
