Take your grilling game up a notch with a brand new Universal Cast-Iron Replacement Grate. Create a sear zone using one cast-iron grate that gets hotter and retains the heat for deeper sear marks. Or replace all your grates with cast-iron to distribute heat across the entire grilling surface for evenly cooked food. And as much as you love your trusty old cast-iron grates, it may be time to upgrade with a new set.
