The Blackstone Natural Gas Conversion Kit with Wind Guards allows you to convert your propane griddle to a natural gas griddle quickly and easily. The wind guards help block annoying winds to prevent flames becoming extinguished while you are cooking, and the long hose is durable enough to remain resilient outdoors and as you move and hook up your griddle. The orifice fittings help you make sure the hose remains secure on the griddle and tank.
