The Char-Broil 18-1/2-inch charcoal kettle grill is everything you need for your basic backyard barbecue. It has 261 square inch of cooking space, on a porcelain-coated cooking grate. The porcelain enamel finish on the lid and bottom, add protection from the elements. We do recommend using a grill cover to extend the life cycle and to prevent unnecessary wear and tear. The vented slide in ash catcher provides circulation for air and heat throughout the grill. For further control of the temperature and cooking, the charcoal grate is adjustable to bring the heat closer to the food or further away as needed when cooking. Two dampers easily control the heat. There are two wheels for easy mobility and a chrome-plated wire bottom shelf for stability and convenience. It"s your basic kettle charcoal grill that you can count on to get your cooking job done.
