It's a two piece cast iron cooking grill for a 22.5" Weber kettle. Those of you that cook on the Weber kettles know that the design of the barbecue itself is peerless but the construction of the cooking grill is uh...not peerless: it's chrome coated, doesn't hold the heat and is too lightweight for some heavy grilling. Enter, our new, rugged, cast iron grill. If you've got a Weber kettle, this grill is a must-have.
