When building in a Sharp countertop microwave oven be sure to use the proper Sharp built-in kit. All Sharp kits are UL approved and provide duct work to assure proper air circulation around the product. The Sharp RK-49S27 27-inch trim kit is compatible with the Sharp SMC1842CS and SMC1843CM microwave ovens. It will provide ventilation as required and delivers a clean look that integrates the microwave into the wall or cabinet.
