Abstract: A smoke producing device adaptably configured for use in either a gas and electric barbecue grill having a plurality of heat diffusers, heat bars or plates, or sear bars (collectively referred to hereinafter as the “heat distribution bar”) principally serving as means to distribute heat and aid in preventing flare-ups within a grilling compartment, the smoker device substantially comprising a rectangular-shaped receptacle having a pair of longitudinal walls positioned perpendicular and integrally attached to a pair of end walls and an inwardly-protruding channel situated between a pair of bottom plate members and extending lengthwise thereabout to form a pair of legs for engaging the heat distribution bar. A detachable top having a plurality of elongate openings allows venting of accumulated smoke as heat is applied to a smoke-producing material contained within the rectangular-shaped receptacle.
