Stainless steel rods 8.5", 10.5", 12", 13", 14", 16" Each rod comes with 3 nuts. I like to have my rods even with the height of my mold, to avoid bumping the rod, while pouring. Stainless steel works best and is not corrosive with lye. Some of the rods will have a light machine oil on them and will need to be washed before use. The 8.5" work great for Dairy Cartons and my small 3" molds. Conversion to Centimeters
