Product review (5 stars): Perfect Fit!
Other replacement drip pans were a less-than-perfect fit for my 1985 Whirlpool range. They looked OK but never sat flat on the stove top, probably due to the higher oven chimney vent on the small back burner.  These pans are very high quality and the larger-than-average opening means they fit like they came with the range from the factory!  And when these drip pans get soiled from burnt-on food residue, I know that soaking them overnight in a sealed plastic bag filled with a half cup of ammonia will loosen all the residue enough to wash it away! I still feel out-of-date for having coils on my stovetop instead of a smooth ceramic top - but my stove looks brand new - and it works so well I may never be able to get rid of it!
