A:Answer Hello, great question! Roller racks can be purchased for use in many ranges and wall ovens that do not already have a roller rack. Roller racks are either nickel or enamel coated, heavy-duty construction and are tested for weights up to 40 lbs (self clean; heavy duty racks up to 50 lbs). Enamel coated racks are self-clean racks and are darker. Nickel racks are a light, shiny metal and can't be self-cleaned. For your 30” Free-standing Double Oven, you could use rack model WB48T10071(nickel) or rack model WB48X20862(self-clean). We hope this information suits your needs, and please reach out with any additional questions!- Kianna@GEA
