Napoleon Grills Cast Iron Charcoal and Smoker Tray

Napoleon cast iron charcoal tray

I have only used this tray once so far. It was simple and straight forward putting it into the grill to use. During the first use, the tray cracked along the right hand side from the edge to a quarter away along the bottom. I noticed this next day when I was cleaning off the ash from the tray to remove it. It is still functional, but I would not think a cast iron tray would crack after the first use.
