Overview
The rundown on the BJ-MFGC Cast Iron Fire Grate for Big Joe 24 Inch Grills
The Kamado Joe BJ-MFGC Cast Iron Fire Grate is the original Kamado Joe replacement fire grate engineered specifically for Big Joe 24-inch kamado grills — including the Big Joe I, II, III, and Pro Series models. Cast from heavy-duty iron to an 11.5-inch diameter, this bottom grate sits at the base of the firebox and delivers the critical airflow management that turns a good charcoal fire into an exceptional one. The thick cast iron construction retains and radiates intense, even heat that is essential for everything from a slow 12-hour brisket smoke to a searing 700°F reverse sear — giving you the fire performance that Kamado Joe's legendary ceramic cooking is built on.
Designed for Australian BBQ enthusiasts who take their backyard cook seriously, this fire grate is the workhorse component that supports your charcoal bed and keeps ash flowing freely through to the ash drawer below. Whether you're running a long low-and-slow smoke for a Sunday lamb shoulder, firing up a hot direct cook for T-bones, or layering in lump charcoal for a weekend gathering, the BJ-MFGC keeps your fire burning efficiently and consistently. It's the must-have replacement or upgrade part for any Big Joe owner who wants their kamado running at its best — backed by the quality and precision fit that Kamado Joe is known for across Australia.
