Its a smoker box, but
"Its a smoker box, but the angle of the bottom tray channels does not match the Broil King heat deflectors. Thus, it wobbles and in not stable as you might expect. Either this box was designed for another heat deflector, or the design is just bad. The material looks good, although the fit of the lid and articulation of the hinge should match better that it does. Overall, this item ranks at a 5 out of 10. It should have been better designed."
