The 20ft MultiStoreBox is a revolutionary flatpack storage unit designed to give self-storage operators maximum rental yield from limited space. Measuring just 7ft 7" deep by 20ft wide, this unit fits neatly at the ends of rows, in awkward gaps, or tight site layouts — where traditional 20ft containers simply don’t work.​​
