To get the correct Costco 21119 BBQ parts
  • You should measure your existing parts and compare them to what we show here. This is best done with them removed from the grill.
  • Verify your Costco model number by checking the CSA appliance tag on your grill to make sure you have the correct model number. Do not rely solely on the owners manual as these are frequently mixed up at retail stores when the grills are assembled. You'd be surprised at how many folks have the wrong owners manual.
