Pair of Char-Broil Porcelain 10 3/4" x 13 15/16" Gas Grill Grate Replacements. My sister bought these in 2011 and used them a few times in the summer of 2011. Next summer she moved and did not take her grill but kept the grate replacements. I just found them in my basement in the original box. I have no recollection of what model grill she had. The product # (in picture 8) is 4152457, but not surprisingly does not come up years later. Grills are in very good but not brand new shape. you'll notice there are some rust and discoloration spots. First pic is top of grills with the next 2 individual pics; pic 4 is the bottom with the next 2 individual shots of bottoms. 

Will ship USPS Ground Advantage w/o the original carton as that is a little too tall to fit in; they're almost 5.5 lbs. To use these you either have a very old grill or the sizes happen to fit.
