PRODUCT DETAILS

Product Description

Split your lump charcoal for two-zone cooking or run smaller, more efficient fires with this OEM Firebox Divider for Primo Oval ceramic grills.

This heavy-duty cast iron divider drops into the charcoal grate to split the firebox in half. Run a smaller fire for everyday cooks, or bank lump to one side for perfect direct/indirect setups.

Why Use a Firebox Divider?

  • Two-Zone Cooking: Keep lump on one side for direct heat while the opposite side runs indirect.
  • Fuel Efficiency: Use less charcoal for smaller meals or shorter cooks.
  • Precise Control: Easily switch between full-fire, half-fire, or dual-zone setups.
  • OEM Fit: Designed specifically for the Primo Oval firebox and Lump Grate.

CGS Recommended Setup

For half-firebox cooks, fire up the left side. This aligns the burn with the lower slider vent and brings in the best airflow—perfect for small, fuel-saving grilling sessions.
