The Presto Canning Rack is the best pressure canning rack because it fits the Presto 16 and 23 quart canners most home canners own, keeps jars off the direct heat of the pot base, and doubles as a divider for double-stacking pint jars. A rack is not optional in pressure canning, jars sitting directly on the bottom crack from concentrated heat and blocked water circulation. The four racks here cover Presto owners, stainless upgrades, and water bath crossover use.
The Presto Canning Rack is the best pressure canning rack for most people because it fits the most common home canners and doubles as a stacking divider for pints. The Roots and Branches stainless steel rack is the upgrade pick if you want a rack that will never rust.

How We Chose These Pressure Cookers Picks
We compared racks on material, jar stability under load, fit with common canner models, and stacking support, then read owner feedback focusing on rust, flex, and jars tipping during processing. Fit and rigidity ranked highest, because a rack that flexes or floats causes broken jars and failed seals.
Key Takeaway: Buy the rack that fits your specific canner first and worry about material second. A perfectly flat, rigid fit prevents more jar breakage than any upgrade in steel.
Best Overall: Presto Canning Rack
Best for: Owners of Presto 16 and 23 quart pressure canners who need a replacement rack or a second rack for double-stacking pint jars. Why it made the list: It is made for the exact canner geometry most home canners use, sits flat without rocking, and the dimpled design supports a second layer of pints, which effectively doubles batch capacity per processing run.
- Key specs: Plated steel rack sized for Presto 16 and 23 quart pressure canners, dimpled surface for jar stability, usable as a base rack or a stacking divider.
- What we like: Perfect fit with no rocking, enough rigidity for seven full quarts, and the double-stack capability for pint batches.
- What we do not like: The plating eventually wears at contact points and surface rust follows, especially if the rack is stored damp.
- Who should buy it: Presto canner owners, full stop. A second one is also the cheapest way to unlock double-stacked pint loads.
- Who should avoid it: Owners of All American or other canner brands, the diameter and fit are wrong, and a rack that slides around is a jar-breaking hazard.
- Common complaints: Surface rust after a season or two of heavy use and occasional shipping bends that need flattening by hand.
- Size note: Check your canner model before ordering, the 16 and 23 quart Presto bodies share a diameter but other brands do not.
- Cleaning note: Dry it fully before storage and wipe with a lightly oiled cloth in the off-season to hold rust at bay.
- Alternative: The Roots and Branches stainless rack costs more but removes the rust problem permanently.
Pressure Canning Rack Buying Guide
Why the rack is mandatory, not optional
Jars placed directly on the canner base sit against the hottest metal in the pot, and thermal shock cracks bottoms out of jars. A rack lifts jars so water and steam circulate underneath, which is required by USDA-aligned canning guidance. If your canner came without one or you lost it, replace it before your next batch.
Material, plated steel versus stainless
Plated steel racks work fine and cost little, but the plating wears where jars sit and rust follows. Stainless racks cost more up front and simply last, which pays off if you process dozens of batches a season. Rust on a rack will not hurt the food in sealed jars, but flakes stain the canner and weaken the rack over years.
Stacking and fit
Double-stacking pints legally requires a rack between layers so the top jars do not rest on lids below. Measure your canner floor diameter and match it closely, an undersized rack lets jars slide to the edge and tip against the wall during the boil.
Safety Notes
- Never process jars without a rack, direct pot contact cracks jars under pressure.
- Place a second rack between layers when double-stacking pints, never stack jar on lid.
- Load and unload jars with a proper jar lifter, rack edges get as hot as the canner.
- Follow tested processing times from USDA or your extension service, the rack does not change them.
What to Avoid
- Racks that slide or rock in your canner, movement during processing breaks jars.
- Thin folded-wire racks that flex under seven full quarts.
- Cake cooling racks as substitutes, most are too small and their feet dent under load.
- Aluminum racks in canners used with acidic water baths, they pit and degrade.
FAQ
Can I pressure can without a rack?
No. Jars must sit on a rack so heat and water circulate beneath them. Jars in direct contact with the canner base are prone to cracking, and uneven heating can compromise the safety of the processing time.
Can I stack two layers of jars in a pressure canner?
Yes, pints and half-pints can be double-stacked in tall canners like the Presto 23 quart, provided a rack sits between the layers and the top layer is offset so steam circulates. Never stack jars directly on the lids below.
Will a rusty canning rack ruin my food?
Sealed jars protect the food, so a little surface rust will not contaminate anything. It will stain the canner water and shed flakes, though, and a badly rusted rack loses strength, so replace it once rust goes beyond the surface.
Final Verdict
The Presto Canning Rack is the best pressure canning rack for most home canners, with an exact fit for the most common canners and double-stack support, while the Roots & Branches Stainless Steel Canning Rack is the rust-proof value upgrade and the Norpro Canning Rack covers occasional batches for the least money.
