Great canning rack for little jars! Use one side for larger jars or flip over to use for smaller jelly jars. Process even more in your waterbath canner by using 2 racks to stack half pint jars. Fits most standard 16 qt and larger stock pots, 10-3/8" diameter. Made of stainless steel, so won't rust. Holds 7 half pint or pint jars, other side holds 4 quart jars. Dishwasher safe.
