• second plate is slidably inserted into a plurality of grooves beneath the first plate so ends of the plates can support the multi-piece flavor bar when adjusted in length to be installed into a grill;
• and
• a removable smoker box, comprising an inverted substantially V-shaped removable lid substantially matching a profile of the first plate and covering the smoker box cutout, and a removable box sized to fit within the smoker box cutout, having an open top and a plurality of outward extending ridges at a top edge of two opposing walls of the removable box and a plurality of user-bendable tangs below the top of the edges, so the removable box can be supported within the smoker box cutout by the ridges or the user-bendable tangs to affect a smoke rate, wherein top edges of remaining two opposing walls of the removable box are inverted substantially V-shaped to substantially match a profile of the first plate, wherein the plates and lid cooperate to substantially form a flavor bar shape.
