For any builder or carpenter, tool storage should be a prime consideration. Tools are a huge investment, and keeping them stored so that they aren't damaged or destroyed is important. In this article, San Diego carpenter Kit Camp takes a look at three tool-storage systems using a format popular in Europe but just beginning to make their way to the United States. These systems use stackable, customizable cases of different sizes. Here, Camp looks at systems from Bosch, DeWalt, and Festool. Camp praises Bosch's L-Boxx for its large footprint, spacious interior volume, and secure stacking and unstacking capabilities; the downsides include thin sidewalls and fewer customization options. DeWalt's TSTAK, says Camp, has strong heavy-duty latches, low cost, and places for labels; it also is less customizable and has a limited size range for its boxes. Finally, Camp says that Festool's Systainers are admirable for their backward compatibility with older Systainer models and for their assortment of inserts and accessories; the big downside for the Festool product is that it is pricier than the other two brands.
