Waterbath Canner: My Jars Won't Fit

Why can't I fit 7 mason jars into my rack?

Not all mason jars fit the same way into our canners. If you have purchased Golden Harvest mason jars, you will not be able to fit the maximum number of jars into the rack. Golden Harvest jars have a wider body, that does not fit into our rack as well. Do not attempt to force them, this may cause the jars to break or cause harm to you. We suggest, if you have more than one brand of jar, to mix them in the rack to give you the most usable space.
