The accessory package includes the lid, propane valve adapter and flexible skewers. This package is for your Volcano 2 or 3 grill/stove and completes everything you  will need to get cooking outdoors. The lid is our most popular accessory and allows more efficient cooking and controls the heat when cooking. The propane valve adapter allows the use of 1 pound propane bottles and makes it easy to take the Volcano anywhere, without lugging around your 20 pound tank. The flexible skewers make cooking shish kebabs on the Volcano Grill easy.
