40-Foot Double Door
Full-length dry van with cargo doors at both ends for pass-through handling.
40 ft
Container overview
The 40-foot double door unit places a full cargo door set at each end of a standard 40-foot dry van. Long material can be loaded from either end, and stored goods stay reachable without unloading everything in front of them.
It is a practical choice for jobsite storage, event and exhibition builds, and any operation where two crews work the same container from opposite ends. The envelope, corner castings and stacking behaviour match a standard 40-foot container.
Both ends need clear swing room, and the second door set adds a small amount of tare weight compared with a single-door unit.
