Inserts and Ceramic Briquetts that we use in our Charbroil 26" kettle grill.
Adding ceramic briquettes and charcoal holders help keep the heat controlled and contained.
Visit Home Depot Char-Diamonds for examples of ceramic charcoal briquettes.
Visit Home Depot Charcoal Fuel Holders for examples of charcoal holders.
Adding a thermometer to the dome and ports for probes to the kettle will allow for easier access and temperature monitoring.
Look for lamp parts for the ports to protect both the kettle and the probe wires.
