Hi Alex: Do you recall if your KK cover for your E310 was #7130, and did the boxed item include some accessories (tongs, grill brush, and thermometer)? Is it still holding up after 5 - 6 years? I see some on OfferUp for $30.... The Weber logo would be nice; however, no so with their priceI bought a KK cover for my Genesis E310 and it fit it perfectly. I was half expecting to be loose and ill-fitting, but that wasn't the case. The two Velcro straps on both sides strap it down under the two side tables very nicely, leaving about 6" of exposed space between the ground bottom of cover. I'll try to remember to snap a pic when I get home tonight. It feels nice as well. Fairly thick and rubber/leather-like. No idea how well it actually performs during bad weather seasons as I store the grill in the garage during our California rainy winters.
