Replacement grill parts to fit Arkla model: GRB20-SL
This page shows all of the parts we know fit model Arkla GRB20-SL. If the part you're shopping for isn't included below, you might find it using the category buttons on the right side of the page. For example, if your looking for a burner and there are none here, click the burner button to see all the burners we have for Arkla grills. You will need to know the dimensions of your existing grids to help you find the right part.

To get the correct Arkla GRB20-SL 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 Arkla 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.
