This accessory is compatible with the GRLLR Korean Barbecue Cook Unit for Tokyo Shichirin. The grill plate of the unit can be replaced with this grill grid so fats, juices and oils do not drip directly onto the charcoal. This prevents flare ups as these liquids drip into the tray which is included in the Korean Barbecue Cook Unit. This way you get even more out of your shichirin.
