We call them “sear stations” for a reason. GrillGrates turn pellet smokers into pellet grills. They trap and concentrate heat and conduct it up the rails for great searing while the valleys sizzle juices for added flavor. On the YS1500, GrillGrates can be used as replacements of the existing grates. Every set comes with a GrateTool which is part fork, part spatula that fits between the rails to get under your food and lift it without scraping.
