This charcoal basket will fit on top of our ashtrays. You can use it in a charcoal grill or in the firebox of our 3/16 smokers. It has two adjustment plates so you can adjust the burn of the charcoal to your preference. In the picture below you can see the way the plates are set it burns the charcoal in a S shape resulting in longer burn at a controlled temperature. Holds approximately 13lbs of charcoal. Estimated burn time is 5+ hours using charcoal with wood chunks sprinkled on top.
