The NATO jerry can pattern, explained

The jerry can is one of the few Second World War designs still made almost unchanged, because the shape solved the problem so completely that improving it means breaking compatibility. Here is what the pattern is and why it still matters to a buyer.

Where the shape came from

German engineers designed the Wehrmacht-Einheitskanister in the 1930s: a 20-litre pressed-steel can with three handles, a cam-lever cap and a stamped cross on each face. Allied forces copied it during the war and named it the jerry can after its origin. The core geometry has barely moved since, because it works.

What the features do

• Three handles. One person carries two full cans, or two share one, and cans pass hand to hand down a line without regripping.
• The stamped cross. Pressed panels let the metal flex as contents and temperature change, without the walls buckling or splitting.
• Flat, stacking sides. The rectangular profile packs without wasted space and stacks stably in a vehicle or a store.
• An air pocket under the handles. A filled can floats, and the space gives the contents room to expand.

STANAG and interchangeability

NATO standardised the external dimensions and the mounting interface, so a can from one maker seats in a carrier, rack or holder from another. That is the practical value of the pattern to a distributor: the accessory ecosystem is shared. A NATO-pattern can and a NATO-pattern holder fit, whoever made each.

The pattern is a shape, not a material

Fortitude21 builds the pattern in pressed steel for fuel, in AISI 304 stainless for water and food, and in aluminium where weight is the constraint. The external form stays constant so carriers stay compatible; the interior is chosen for what the can holds.

What this means when you buy

If your customers already own jerry can holders and racks, a NATO-pattern can drops into them. You sell an upgrade, not a reason to re-buy mounting hardware. Browse the fuel and water ranges.
