About the M-2
A twenty-foot main-deck box container built to the AGA code — one of the heaviest-rated units in the ULD system.
At 11,340 kg and 33.7 m³ behind a solid door, it is effectively a small shipping container for the air. It shares that 11,340 kg ceiling with the M-6 and M-6H pallets, but as an enclosed unit rather than an open one. The enclosure costs a tonne of tare, the highest of any general-purpose ULD.
What it carries
How it is built
- A twenty-foot main-deck box container.
- The door is solid.
- A heavier structural section than lower-deck equipment, sized to fill the main cargo deck of a freighter or Combi.
- Rectangular or upper-contoured in profile, depending on where in the deck the unit is positioned.
- A solid or canvas door with net straps, and base rails matched to the main-deck restraint system.
Why it is used
- Far higher gross weight and volume per unit than any belly-hold ULD.
- Loads through the main cargo door in one lift, which is what makes freighter turnarounds fast.
- Suits dense or bulky consignments that would otherwise need several lower-deck units.
What to check before booking
- Loadable only on freighters and Combi aircraft that have a main-deck cargo door.
- Some positions accept centre loading only, which limits where the unit can be placed.
- Handling needs main-deck loaders, so not every station can accept it.
