The Flatpit was designed to accept these extra long skewers. Angled notches along one side of the Flatpit are there for the skewers to locate in while cooking. This way, if your food isn't perfectly centered on the skewer, it will not rotate to expose only the heavy side to the flame. This is our solution to kabobs that tend to be unevenly cooked with one side getting scorched while the other remains raw or cool. We recommend using skewers whenever trying to avoid the clean up a cooking grid sometimes requires. A quantity of 7 come in each set as there are 7 skewer slots on each Flatpit.
