If you're going the extra mile to infuse your food with delicious flavors of natural wood smoke, why not double your output with the same amount of effort? This ingenious device, with its additional height and tray, gives you two options to maximize your Kettle Smoker: Add a second aluminized steel rack to smoke two layers of food at once, or just use the extender alone to add 3" of height for large food items such as a whole chicken, a large roast or a holiday-sized ham. For use with Nordic Ware's full-size Stovetop Kettle Smoker.
