This submersible stainless-steel canning rack features an outer diameter ring to prevent jars from touching the sides of a hot water bath or pressure cooker. Notched handles rest on the pot and allow safe and easy removal of all the jars at the same time. Turns a 20-Qt. stockpot into a canner. Hand wash. Holds 7 one-quart or 8 one-pint size standard jars.
