Monoflo foldable stack-only containers are automation totes on a 650 × 450 mm footprint that fold flat when empty. They run through a system like a rigid tote and come back at a fraction of the volume.
| Model | Outside (L × W × H) | Inside (L × W × H) | Weight | Per pallet | Per 53 ft trailer |
|---|---|---|---|---|---|
| FSO 6545-320 | 650 × 450 × 320 mm (25.6 × 17.7 × 12.6 in) | 610 × 410 × 304 mm (24 × 16.1 × 12 in) | 3.4 kg (7.5 lb) | 170 | 4,420 |
| FSO 6545-325 | 650 × 450 × 325 mm (25.6 × 17.7 × 12.8 in) | 610 × 410 × 309 mm (24 × 16.1 × 12.2 in) | 3.45 kg (7.6 lb) | 170 | 4,420 |
Both models fold to 88.5 mm, about 3.5 in, and ship 170 to a 53 × 43.5 in pallet. The two differ by 5 mm of height, so order the one your system drawing names.
Open, an FSO 6545 stands 320 or 325 mm. Folded, it is 88.5 mm, a little over a quarter of that, so roughly three and a half folded containers fill the space of one open container. That matters wherever empties travel: back from stores, between buildings, or into storage between seasonal peaks. A rigid stack-only tote returns at full height.
| Type | Empty return | Best where |
|---|---|---|
| Foldable stack-only (this page) | Folds flat | Empties ship long distances or are stored for long periods |
| Stack-and-nest | Nests inside the next container | A tapered wall is acceptable and no folding step is wanted |
| Stack-only | Full height | Totes stay inside one building |
Straight walls give a foldable container the same inside length and width top to bottom, 610 × 410 mm on these models, which a nesting tote cannot offer.

To 88.5 mm, about 3.5 in, from an open height of 320 or 325 mm. The manufacturer lists 170 folded containers per pallet and 4,420 per 53 ft trailer.
It is built for automated handling and stacking, but rated loads differ by model. Check the rated capacity of the exact model against your heaviest tote and stack height, and confirm the base suits your conveyor or shuttle.
