Fits my Genesis 1000 (1999 model) propane grill perfectly. I read the reviews where some had to notch the lower bars in order to get the top 8 bars to sit in their slots properly. I was prepared to do that, but it wasn't required. All 13 of my bars fit the Genesis 1000 grill body perfectly. They are made of decent gauge of stainless steel, and after 2 grill sessions, I am very pleased. They have taken on a blue tint from heat and grease drippings, but have not warped at all. I am counting this…

I need to change the flavorizer bars every few years. I have used the manufacturers product and these 3rd party products. For the price difference, these Hongso are a better value.
