Let's make this even more confusing, I ordered this for my Weber Summit grill, made by Flame Tech grills for a number of purposes on the Weber. It's a drip pan, water pan, and the 4 in high wall is for piling charcoal in front to split for two zone. Useful little gadget well made from 403 SS, has all the numbers backwards, but obviously of a cheaper grade. It's 17.5 inches wide, 4 inches at the high wall, 1 1/2 inches lower wall and 11 inches from the high wall to the lower wall center arc. They may sell these on Amazon now, at the time I spoke with the manufacturer. Excuse the dirt, it's been sitting outside for the last 4 months.
