The double walled stainless steel lid captures the warmth from four stainless steel tube burners, circulating heat and producing an oven-like effect. This makes the LEX485 ideal for searing over high heat, roasting, or smoking. You can even bake desserts and bread. The four bottom burners provide even heat for controlled grilling. Go from searing to indirect grilling with ease. Grill up to 24 hamburgers over 48,000 BTU’s. With the LEX485 it is easy to feed a crowd. The JETFIRE™ ignition system ensures that you light the grill quickly and easily every time. Extend your cooking area from the kitchen to outdoors with the LEX485.
