— 20-foot · Duo-Con

20-foot Duo-Con containers — two separate compartments in one shell.

A 20-foot container divided into two independently lockable compartments by an interior partition wall. Each half has its own cargo doors. The same external footprint as a standard 20ʹ GP — two storage units in the space of one.

— Common use cases

What operators use the 20ʹ Duo-Con for.

  • Two separate storage rooms for different tenants or projects
  • Tool/parts split with cargo split, locked independently
  • Multi-trade construction site storage
  • Modifications with two separate end-uses
— Important notes

Caveats and details worth knowing.

  • Specialty configuration — built to order, not commonly held in depot stock.
  • Interior partition wall reduces total cubic capacity vs. a standard 22G1 (approximately 31 m³ usable across both compartments).
— Grades we carry

Available across our condition grades.

New-build production runs are NEW (one-trip) by definition. Used inventory in the 20ʹ Duo-Con format is held in depots at varying grades — exact availability in the live matrix.

  • IICL — survey-grade, pulled from active fleets
  • CW — cargo worthy, CSC-valid for international
  • WWT — wind & watertight, storage-grade
  • AS-IS — sold as-found, no guarantee
