Product review (5 stars): These GE OEM drip pans were a perfect fit
These OEM drip pans were a perfect fit for our GE range.

For anyone trying to cross fit between brands or models, this set contains two WB31M20 6 inch black porcelain bowls and two WB31M19 8 inch black porcelain bowls.  The outer rims of the bowls measure wider than the burner coils, of course.  The 6-inch bowl measures 7-9/16" from edge-to-edge.  The 8-inch bowl measures 10-1/16" from edge-to-edge.
