The best outdoor kitchen you can design is a safe and reliable one. Often times, BBQ Islands and Outdoor Kitchens are built using a mixture of combustible materials (lumber, plastic, resin, and other combustible materials), without proper protection, these materials can burn and may catch on fire, that's where an insulated grill jacket comes in. Insulated Grill Jackets are self-rimming stainless steel sleeves that fit the make and model of our grill, exactly. Insulated grill jackets are self-rimming, meaning they are built into an outdoor kitchen just like a typical grill. Once the insulated grill jacket is installed, simply place your built-in grill into the sleeve and connect your gas line and electrical hook-ups as usual. Insulated grill jackets are required by law to be used if an outdoor kitchen is being constructed using any combustible material (lumber, plastic, resin, and other combustible materials). The Summerset Grills insulated jacket (GL-TRL38) is a safety essential when installing your Summerset 38-inch 4-burner TRL Series built-in gas grill into an outdoor kitchen or BBQ island that is constructed of combustible materials. This insulated jacket is constructed of stainless steel with a self-supporting ledge around the sides and back that adds one more layer of quality to your outdoor kitchen.
