Product review (5 stars): Exact match for Whirlpool WCG97US0DS cooktop
I have the Whirlpool stainless five burner cooktop with the hinged grates model no. WCG97US0DS.  The plastic ring on the underside had cracked, causing a loose fit and to turn without actually turning the prong that controls the burner.  I bought this set to replace them, and they are a perfect fit and exact match.
