All American Canner Base Upgrade Kits
Two Sizes. One Lid. All American Base Upgrade Kits.
One lid. Two bases. Turn One Canner Into Two.
With All American's unique interchangeable design, you can turn a single canner into two sizes — without buying a full second unit. Whether you're upgrading your current All American canner or purchasing your first, these Base Upgrade Kits make canning smarter, more efficient, and space-saving.
How It Works
Models 915, 921, 925, and 930 all share the same lid and gasket-free seal diameter. That means the lid from any one of these models fits the others perfectly — same precision diameter and metal-to-metal seal.
➤ Already Own a 915, 921, 925, or 930?
Add a new base. Keep your current lid and simply swap between two canner bodies to handle small or large batches.
➤ Buying Your First All American Canner?
Build a Two-in-One Kit. Start with one lid and select two bases (like 921 + 930) so you can handle different batch sizes from day one.
Why Upgrade to Two-in-One?
Choosing the right size canner can be tough — and it's not just about your kitchen. It depends on the garden, the grocery store, or whether you're hunting duck or deer this week.
Sometimes you've got 50 pounds of tomatoes. Other times it's just the stew leftovers. And let's be honest — sometimes your plans change because ground beef was on sale for $2.49 a pound.
• Save $194 not buying a second full unit• Efficiently process big or small batches
• Reliable fit — all components are precision-machined by All American
• Grow into it — start with one base, upgrade later
