Wonder how we got the same Avitar?
I have GG's for my Blaz'n GS. They are wonderful. They retain heat and actually get about 50* hotter than the original grates (unless you have cast iron, but even then GG's out perform due to the design). You can measure the depth of your original grates and then order from them on the website. I ordered mine 1" shorter, so I could just place them on top of the original grate with space at each end to allow the proper circulation of the convection air. I ordered 3 grates so I could do steaks, burgers, etc for several people at once. They will send the special spatula as well with the package. They also have a SS steel coil brush to use inside of the valleys, it is a must although hard to clean. Here is a recent cook. Lamb chops.
