By having the lit fuel in two moveable holders on the charcoal grate, you are able to move them around to create different heat zones in different areas of your grill.
This will make the ash fall off, and the briquettes are ready to be re- used.
When you barbecue with indirect heat using the Weber charcoal fuel holders, they must be positioned at the sides of the barbecue.
Char-Baskets come in a pair and are designed to sit on top of the charcoal grate with all 57-cm Weber charcoal barbecue models.kk
