I was just perusing your site (after you posted a pic of that grill extender that you will be hunted down and killed for if you don't give us more information about<g>) and came across these images:[p]http://www.tm52.com/bge/grate1.jpg
Is there any fear of the metal in these expanding and cracking the firebox? Forgive my ignorance of metalurgy, I would assume you wouldn't use it if it would cause any problems. I just didn't want to run out and get one of these babies if there were potential problems to be concerned with.[p]Thanks,
P.S. Very informative site. Great Job!
