If you're looking for replacement parts for your Weber - and, you don't want to burn a hole in your wallet - then you'll want to get yourself a set of Grill Care Flavour Bars. This set includes 5 stainless steel flavour bars which are compatible with the Weber Spirit™ 200, 500, and Genesis™ Silver A series of gas grills.
You may be thinking, "Hey, that box isn't branded by Weber!" Although that may be true, the stainless steel bars within the box are virtually identical. In fact, these guys weigh a tad more. So in this case, less is more!
