Use our handy Firebox Divider in your Primo Oval XL or Oval Junior to partition the firebox. This allows you to cook using direct heat on one side of the grill and indirect on the other side! Or it will allow you to only use half of your grill for smaller cookouts. (Note: Shown here in the lower grate which comes with your grill; it is not included with the Firebox Divider).
