Why this size exists
Same footprint, rotated call-out. Automotive plants tend to write the 40 first because their pallet spec lists the stringer direction first — the box is identical to a 48×40×45.
What it is used for
Automotive interiors, converted foam, bulky returns.
Wall count matters as much as footprint here. This size is stocked in 4-wall, and the capacity range of 2,400 – 3,400 lb spans that spread — the low end is the lightest construction, the high end the heaviest. Pick from the actual weight of a full box, not from the catalogue maximum.
Material density check
At 50 cubic feet, this box fills completely at these bulk densities before it reaches its weight limit:
| If your material weighs | A full box weighs | Verdict |
|---|---|---|
| 10 lb / cu ft | 500 lb | Volume-limited — consider a taller wall |
| 20 lb / cu ft | 1,000 lb | Volume-limited — consider a taller wall |
| 35 lb / cu ft | 1,750 lb | Well matched to this size |
| 50 lb / cu ft | 2,500 lb | Well matched to this size |
Rough guide: shredded film and foam sit around 4–10 lb/cu ft, mixed textiles 8–14, plastic regrind 20–35, e-scrap 35–60, and minerals or aggregate well above that. At 30 lb per cubic foot this box hits 1,500 lb exactly full.

About 390 knocked down per 53-foot trailer. Assembled on pallets you get 26 pallet positions instead — roughly a quarter of the boxes for the same freight bill.

Is 40" × 48" × 45" an inside or outside dimension?
Inside. Outside dimensions run roughly ½" to 1½" larger per side depending on wall count, which matters for racking and trailer fit but not for what you can put in the box.
Can I get this size in a different wall count?
We stock this footprint in 4-wall. Other wall counts are available as new builds, or occasionally we can cut down a taller box to this height from heavier stock.
What pallet does it need?
A standard 48" × 40" GMA pallet. Match the footprint exactly — overhang removes support from the corners, which carry most of a stacked load.
