You can purchase them for weber it is not worth the price just so you are aware. I lost my 14.4 one and they wanted to charge me upwards of 60 bucks not to include shipping. With that being said I just went out and purchased some expanded metal and did it that way, it cost me less than 10 bucks and about 30 mins of my time. Although this way only lasts 2-4 years depending upon use I figured it was better than shelling out the 60 bucks for how long of use? That way if I lose it again or something happens I am only out another 10 bucks rather than 60+.
