Crawdaddy, I just kind of measured my fire grate. It looks to be about 16" dia. It can't get an accurate measurement as I am TRexing some steaks. I have that LAVA look going on.Mike in AbitaP.S. If your wondering about TRex than I suggest going to The Naked Whizes web site. It's a really cool site that has helped me out on numerous occasions.
