This didn't fit in my grill until I made some modifications with a hammer and pliers. Now it fits fine. It's pretty thin steel. I don't know how long it will last at high temp.
Considering that it would have cost about the same for me to get a blank piece of stainless steel at my local hardware store and have to do ALL the shaping myself... I guess I came out ahead by having it already the right width and tent shaped. But don't expect to "plug and play".
Oh yeah, it came out of the box bent (the wrong way). It is too thin and not correctly protected. If it was thicker steel it might have survived better.
