Product review (5 stars): Fits non-Whirlpool models too.
I've used these on two old, non Whirlpool stoves now and they fit both perfectly.  Most recently I moved to a new house with a Frigidaire stove which was equipped with some hardware store replacements that did not fit at all.  The small bowls were too big and the burners were at an angle.  These fit perfectly and now the stove looks like new and my pans are level!  I can't guarantee these will fit everything but they've worked for me twice now.
