The Smokin Brothers Long Grid Insert is designed to fit the front or back of the top shelf on Traditional or Premier grills. Compatible with 20", 24", 30", and 36" models, it offers versatile placement to enhance your grilling setup. For owners of Premier Plus grills, be sure to select the Premier Plus size, as these models require a slightly different grid dimension. This insert provides a durable and reliable surface to expand your cooking area or keep food warm during grilling sessions.
