Summary Every time I use my propane torch, I worry that it will fall over. This provides stability to the tank and keeps it from falling. v2.2 is the one shown as the main picture. I has the base that uses less plastic and the cylinder is 2 inches tall versus the original 3 inches (v 2.1). The 2 inch version saves plastic and works well, the original 3 inch version feels a bit more stable. Either should suffice to keep the tank from falling while ablaze.
