Fitz-All Set of 2 Replacement Pot Knobs, Wide – Click Here! – I just bought these pot knobs and now I wonder why it took me so long! I melted the handle on my crock pot years ago and it was a pain to grab it in order to lift the lid. I couldn’t find a replacement knob for the Rival Crock pot, so everytime I used my crockpot (maybe once or twice a month), I would take a screwdriver and unscrew the knob on my dutch oven and screw it onto my crock pot. At least I was fortunate to have another knob that fit.
