The Mt. Shuksan Charbroiler features a “heat sink” style firebox; cast from our dense, durable high-temperature ceramic and is contained within a heavy-duty, insulated, stainless steel cabinet. The Mt. Shuksan is designed to store and radiate heat evenly. The grill is comprised of 6-inch x 24-inch sliding cast iron grates which rest on a warp-resistant, stainless steel frame. The grates slope upward toward the back of the firebox to allow for easier grilling. A relatively small amount of fuel (seasoned hardwood or hardwood charcoal) will keep the entire firebox saturated with heat, which is evenly radiated up to the grill surface.
