Primo Cast Iron Firebox Divider for Oval X-Large

Will this divider fit my Primo Oval X-Large?

Yes, it is sized to the Oval X-Large firebox. Primo lists a different divider for each Oval, so the X-Large part will not fit a Large or a XX-Large and their dividers will not fit yours. The size in the title is the one to match.

What is the difference between a firebox divider and a heat deflector?

A divider sits down in the firebox and controls where the charcoal burns. A deflector sits above the fire and stops that heat radiating onto whatever is on the grate. One manages the fire, the other manages what the fire does to your cook, and most indirect setups end up running both at once.

How many pieces are included?

One. The X-Large divider is a single cast iron piece and that is the whole item, with no second half to buy alongside it. Both the deflector plates and the deflector rack for the Oval X-Large are two-piece listings by contrast, so piece counts are not consistent across the indirect parts for this grill.

Does the divider work with the half drip pan?

It does, and the pairing is natural. Both are half-of-the-grill parts: the divider keeps the fire on one side, and a half pan sits over the other to collect fat and juices. The Primo Half Drip Pan Oval X-Large is the matching size.

Will a two-zone fire on its own let me cook low and slow?

It gets you part of the way. Moving food away from the coals helps, but on a ceramic grill the dome still radiates and the food is not shielded. For a proper low-and-slow cook, add a heat deflector so nothing on the grate is in the fire's direct line.
