Replacement BBQ grill parts for Weber model: Summit 450
This page shows all of the parts we know fit model Weber Summit 450. We might not show the part you need here but we may still have it, or a functional equivalent. In this case, try the category buttons on the right. For example, if your looking for an ignitor, or other ignition components, and there are none here, click the ignition button to see what we have for Weber grills. Knowing the dimensions of your existing part will help you find the right part.

To get the correct Weber Summit 450 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 Weber 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.
