Gas Grills are considered by many to be the most convenient way to grill but unfortunately this usually means giving up great smoky flavor for convenience. The Charcoal Companion Smoker Box features a V-shape bottom which allows it to sit between the flame deflector bars of most gas grills. This positions the smoke right beneath the food grate for the most intense smoke flavor. Durable, nonstick coated metal smoker box has a hinged lid and is reusable. Add wood chips of your flavor choice and place between the flame deflector bars on the gas grill (wood chips not included).. V-shape fits between flame deflector bars on gas grills for the most intense smoke flavor.
