If you would like assistance in ordering parts please Email us at info@edyoungs.com with your Weber grill's serial number (2 letters followed by numbers) and we will be happy to let you know which part(s) you need. The serial number should be on your grill. Sometimes it will also be on your owner's manual but please verify you are looking at the correct manual for your grill. Weber made many different grills over the years and it is a bit confusing figuring out which parts to purchase.
