Primo Cast Iron Firebox Divider for XXL (PG00371): Create Dual Cooking Zones in Your Primo Grill

Primo Cast Iron Firebox Divider for XXL (PG00371) is designed to give Primo Oval XXL grill owners greater control over heat management and charcoal use. By dividing the firebox into two separate sections, this accessory allows you to run distinct cooking zones so you can grill with direct heat on one side while cooking low and slow with indirect heat on the other.

Constructed from heavy-duty cast iron, the divider is built to withstand the intense heat generated inside ceramic grills while delivering long-lasting durability. Once installed, it partitions the charcoal bed, allowing you to precisely control where heat is concentrated inside the grill. This flexibility makes it easy to sear steaks at high heat while simultaneously roasting vegetables, smoking ribs, or finishing thicker cuts of meat at lower temperatures.
