A firebox divider is a handy tool that is inserted into the bottom grate of your grill and actually divides your grill in half.
It is a perfect solution for grilling for a smaller group, plus it allows you to cook using direct heat on one side of the grill, and indirect heat on the other side.
This firebox divider is made specifically for use with your Oval LG 300 Primo Grill.
Note: Product photo shows the cast iron divider as it is installed with the lower grate, which comes with your grill. Divider does not include grate.
