Primo Cast Iron Firebox Divider for Oval Large

Will this divider fit my Primo Oval Large?

Yes. It is made for the Oval Large firebox and is not interchangeable with the Junior, X-Large or XX-Large versions. Each size gets its own divider because the fireboxes differ, so check the size name on the listing against your grill.

Why would I burn charcoal in only part of the firebox?

Because most cooks do not need a full fire. A smaller charcoal load comes up to temperature faster, burns less fuel and leaves you an unlit section that acts as a cool zone. It also means you are not left with a grill running hot for hours after a twenty-minute cook.

Is this one piece or two?

One. The Oval Large divider is a single cast iron piece and that is the complete part. There is no second half to order and nothing to put together before it goes into the firebox. The deflector plates and rack for this same grill are two-piece listings, so do not assume the counts match across a basket.

Can I use the divider and a heat deflector at the same time?

Yes, and it is a common setup. The divider controls where the fire burns and how big it is; the deflector blocks the heat coming off it. Running both gives you a small, contained fire and a grate that never sees direct flame.

Will a divider save me charcoal?

It should, on any cook that does not need the full firebox. Lighting one section rather than the whole box means less fuel burning, and the unlit charcoal on the other side is still there for next time rather than being consumed along the way.
