Old cast iron burners had rusted out. Went with these stainless steel versions. Looked good upon arrival. Unfortunately, the post at the bottom far end is located further out than the original so they do not sit low and lock into these holes. Still seem to work just not fully correct.
Does what they are supposed to do. The flame holes in these burners are a little larger than my previous Jennair factory burners. This lets the top temp of the grill achieve almost 100 degrees more than the factory burners did. Almost scary hot - 650+, so I just throttle the burners back to be where I was. But that extra 100 degrees plus a pizza stone makes for better grilled pizzas though.
I like these burners a lot, if they last. One came without a screw as shown in picture. They each came with a hose clamp for what I have no idea, maybe a different model application. No instructions for install or adjustment. I will update as time goes on.
VERY nice replacement for aging and rusted original burners
Basically turned my $2500, 15yo Jenn-Aire grill into a new grill again! Beautiful works of art that restore your grill to it's glory days (and won't fade into rust like the steel burners).. Everything is stainless steel now from inside to out! Love it. Well worth the money.. A+
