The Frontier grill has an angled double lined lid which locks in the heat while keeping the exterior of the lid from becoming searing hot, a great feature for those with curious kids! The Frontier is safe, easy to use and like all Kenyon grills, flare up and smoke-free. Engineered for indoor or outdoor use, unlike any other grill available. The grate is coated in the longest lasting medical grade non-stick coating available and is PFOA free. The lid, grate and drip tray can all be cleaned easily by placing in the dishwasher to keep your grill looking like new for years to come. Most grills have hot and cold zones that do not allow the use of the entire grilling surface.
