This makes it a brand new grill
The packaging to keep it safe in transit was clever. It arrived when promised. The swap out took under 30 minutes once I was able to get the screws back in. The grill runs like it's brand new!!! It was 25F out and the grill got to 600 very quickly. Best value!

Perfect Fit
I needed this part to repair my 2012 Weber Summit Grill. Which is the beauty of owning a Weber grill. I'm hoping to get another 10 years out of my grill with this new part. The part fit perfectly and the grill is back to performing flawlessly!
Thank you.
