Troy, thank you. You just made me feel a little better! Sorry it's at your expense!
It's on the back panel. If you are looking at the front, you see where it says Weber? It's pretty close to opposite of that on the back. If you don't have access to the back of the grill, it may not be functional.
I was really considering buying a 3rd set of tool holders to hold the grate to go with my 2nd set I already crimped to the lid holder for extra tools (Brush, charcoal tongs, scoop).
