The metal basket creates better airflow under and around the fire.  In addition, it allows smaller bits of charcoal to fall through, also inproving airflow.  It’s also 'grate' for shaking ash off of residual charcoal or just removing the heat source after cooking. Our basket also comes with a central didivder to control the amount of fuel used and create a heat zone.  Note: remove cast iron ash grate before use.
