It’s made of tough, thermally stable ABS and it’s built strong, sturdy and compact. All locks and handles are recessed. The lid latches of the Systainer also latch one Systainer to another. This Festool patent has a great practical benefit – the user can latch several Systainers together and carry them as a single unit. This means fewer trips back and forth to vehicle, saving time and hassle. All Systainers have the same base dimensions, matched to Euro pallets. This means that Systainers fit together flush, even when units of different heights are stacked together, for the most efficient use of space in transit and storage.
