Do you happen to know if this will fit a nexgrill deluxe 6 burner grill

You can determine whether or not a spit rod will fit a grill by measuring the distance between the notches that hold up the spit rod. These will be on the right and left side of the grill body. You'll need 1"-2" extra on either end. So if your grill measures 34" from one notch to the other, this 36" spit rod would fit. Hope this helps!
