I love cooking on CI. When we moved in, there were some really nice CI grates by a fire pit in the yard. I'm using one of them in my Weber kettles where it is a perfect fit.
You can't really see in the picture but that's a hinged grate and there is just enough space to open the sides up. the CI grate itself is 3/4" tall and the spacing on the bars is tight enough to prevent those escapees that like to slip between the grate bars and into the fire.
If I didn't have this, I would probably have a Stok or Craycort or one of the other popular CI grates.
