Pressure canning is the only canning method recommended safe by the U.S.D.A. for low-acid foods such as vegetables, meats, and fish. The easy-to-read dial gauge automatically registers a complete range of processing pressures. Air vent/ cover lock allows pressure to build only when the cover is closed properly and prevents the cover from opening until pressure is safely reduced.

Canner is constructed of extra strong, warp-resistant aluminum and is suitable for use on regular and smooth-top ranges. Includes cooking/canning rack and complete instruction and recipe book.
