The Systainer³ is similar to the T-Loc Systainer, but with a number of upgraded features. This will be the third generation Systainer tool box. The first, Systainer Classic, connects to other Systainers via 4 latches and opens or closes with 2. The Systainer T-Loc greatly simplified things by featuring a single rotating latch that can be used to open and close the tool boxes and for stacking. Thanks to the wide variety of bottom and lid inserts the Systainer³ can be adapted to your individual requirements. It is fully compatible with T-Loc Systainers and cal also be integrated with the Classic tool boxes.
