Blaze Professional Smoker Boxes allow you to achieve the smoked flavor everyone loves with the convenience of your gas grill. The Blaze Professional Extra Large Smoker Box infuses foods with even more smokey flavor than the original, now with a wider, cooking grid-width design. The extra large smoker box is designed to be placed directly under the cooking grates and adds outstanding smoky flavor to grilled foods, with no charcoal mess. You can also add your favorite juice, wine or marinade to this sealed bottom box to add extra flavor and moisture to your meat. This smoker box is made with solid, heavy duty 304 stainless steel which will remain durable under high temperatures. The bottom box has a hole on one side to allow access to the backup flash tube ignition without removing the smoker. Designed for use with Blaze Professional 27-inch 2-Burner, Blaze Professional 34-inch 3-Burner, or Blaze Professional 44-inch 4-Burner gas grills. Not for use with Blaze Original Grills.
