Yes, the Fitz-All 63458 is adjustable and designed to fit round cookware from about 6" to 11" in diameter, so it may fit an 8-qt Farberware pot. However, I can’t confirm that its included screw matches the smaller mounting holes on your Farberware pot. The handle comes with one replacement screw, so the safest option is to compare the existing screw diameter/thread before ordering.
