Expand your cooking versatility with this Cast Iron Firebox Divider, designed specifically for the Primo Junior (JR) grill. This single-piece divider lets you split your firebox into two separate heat zones, giving you the ability to run direct and indirect heat simultaneously — a game-changer for meals that require different cooking methods at the same time. Crafted from durable cast iron, this divider is built to withstand the intense, sustained heat of ceramic kamado-style cooking. Cast iron's excellent heat retention ensures a clean divide between zones without sacrificing temperature stability on either side. Whether you're searing a steak over high direct heat while gently smoking vegetables on the other side, or maintaining a two-zone setup for foolproof barbecue, this divider makes it easy to manage your cook. Installation is straightforward — the divider fits directly into the firebox of the Primo JR grill, making setup and cleanup simple. At just 3 lbs, it's substantial enough to stay firmly in place during the cooking process while still being easy to handle. For Primo JR owners looking to get more out of every cook, this firebox divider is a practical, well-made addition to your grilling toolkit.
