This is a direct replacement of the factory grate. The factory grate is 14ga mild steel and is well know for burning out with continued use. So i made one that is 12ga 304 Stainless Steel which should last the duration of the grill. This mod goes well with the firebox mod because you have to take the firebox mod out to install this. This is a great way to preserve your grill.
This is not a must have but the work that goes into intalling the firebox mod it just makes sense to do it at the same time as the firebox. Or if you wait to do it you will wish you did it when you have to take it all back apart to put this in.
Fits all models 560, 800, 900, 1050
