What are the two unnamed parts that came with new Char-Broil gas grill?
I just bought the same grill earlier this week. The second item is a match holder as moscafj mentioned. The first is used when assembling the bottom of the cabinet: the two pins slot into a pair of holes on each wheel mount, which locks the wheel in place allowing you to screw the wheel in. After the wheel is in, you remove the pin to allow it to freely rotate.
