Unlock the full versatility of your Primo kamado grill with the cast iron firebox divider. This heavy-duty accessory allows you to split the firebox into two distinct cooking zones—perfect for simultaneous direct and indirect grilling.
Use one side for high-heat searing and the other for low-and-slow cooking, or conserve lump charcoal during smaller cookouts by fueling just one side. Designed to fit securely in the center of the firebox, the durable cast iron construction ensures long-lasting performance and efficient heat management.
Whether you're cooking for a crowd or just a few, the firebox divider adds flexibility, fuel efficiency, and greater control to your grilling setup.

Primo Ceramic Grills
Primo is the only ceramic grill made in the USA, making it a top choice for American grillers who value quality and domestic craftsmanship. Its patented oval design sets it apart by allowing true two-zone cooking, so you can grill and roast at the same time—something round ceramic grills can’t truly match.
More than just a grill, Primo functions as a grill, oven, roaster, and smoker, giving you the flexibility to cook everything from steaks to brisket to fresh bread. Its ceramic shell combined with 100% natural lump charcoal delivers unmatched flavor and juicier results that gas and metal grills simply can’t replicate.
