The heavy-duty cast-iron Firebox Divider from Primo allows you to split the fire-box area to create two distinct cooking zones for simultaneous direct and indirect cooking allowing you greater flexibility to adjust the cooking of your food. Indirect side roasts tender foods like vegetables and seafood to infuse wood-fire flavor without charring. It also conserves the amount of natural lump charcoal needed when only half the grills cooking area is needed. Place the Firebox Divider in the slotted areas of the charcoal grate to stand it vertically on the grill. Models: Oval JR 200, Oval LG 300, Oval XL 400.
