A Systainer is a stackable, modular storage case system engineered and manufactured by Tanos in Germany. It shows up everywhere in this community’s fitouts — vans, workshops, job sites, even a mobile pizza operation — for a few specific reasons that keep coming up when people explain why they chose it.
Systainers are molded from ABS plastic, engineered to be as light as possible without giving up rigidity. That difference shows up before you’ve put a single tool inside — it’s the weight of the empty case itself. Several people who’ve made the switch from other systems point to exactly that moment as what convinced them.
William Kucharski, who runs Front of House sound at his church, switched his cable and gear storage from Milwaukee PACKOUT to Systainer³ and put it simply: PACKOUT “worked, but the cases took up a lot of space, and the closures made it frustrating to get in and out quickly.” Two Dog Pizza made the same move for a mobile catering setup that has to fit in a VW Tiguan.
Systainers come in a range of footprints designed to stack and interlock with each other, so a fitout can be built exactly to the space available — a van shelf, a workbench, a backseat — without wasted volume. Given that design, it’s hard to find a toolbox system that packs more usable storage into its footprint.
That’s not just a claim — it’s what happened when Two Dog Pizza rebuilt his mobile pizza setup around Systainers: the new setup holds 95% of his previous gear in 40% of the space, both in the vehicle and back on the garage shelves.
Systainers aren’t one-size-fits-all, either. The lineup spans a wide range of footprints and heights that all stack together, and many models offer color options for the body, catch, and handle — so a fitout can be sized and styled to match the exact job, not just made to fit it.

Tanos launched the first Systainer — what the community now calls the Classic — in 1993. Over 35 million have been produced since, across three design generations (Classic, T-Loc, and the current Systainer³), and the four-catch stacking mechanism from that original 1993 design still works with Systainers being made today. A Classic Systainer, a T-Loc, and a Systainer³ stack together without a second thought — see all three stacked.
Festool popularized the Systainer by using it as the case system for its own power tools. Since then it’s grown well beyond Festool — Tanos calls a brand that packages its own products in Systainers a System Partner, and there are now hundreds of them. Mirka, Veritas, and Mafell are three examples, each shipping their products in Systainers bought from Tanos with their own branded colors, molded logos, and custom inserts. A Systainer made for Festool and one made for another System Partner are still fully compatible with each other — same stacking design, same catches.

A System Partner ships products in Systainers. A Systainer Partner is different — it’s someone who makes things compatible with Systainers: mounting hardware, racks, organizers, or professional fitout work, built specifically for the Systainer footprint. Real examples are tagged Systainer Partners on this site — that ecosystem is a big part of why fitting out a Systainer setup is so approachable, whether it’s a first stack or a fiftieth.
Fitouts on this site come from a lot more than woodworkers and tradespeople. Real submissions come from anesthesiologists and other medical and dental professionals, electricians, plumbers, HVAC techs, automotive work, carpentry and woodworking, photographers and other creatives, and even a mobile pizza caterer. If a job needs things organized, protected, and easy to grab, there’s probably already a Systainer fitout for it.
None of this is an argument that you have to give up other storage systems to use Systainers — plenty of fitouts in this community run Systainer and Milwaukee PACKOUT side by side in the same van racking, and that works just fine. Systainer just tends to be what people reach for first once they’ve tried it, especially anywhere weight and footprint matter.
Yes. Tanos is part of the TTS Group, which also owns Festool, SawStop, and other well-known tool brands.
Yes. Festool popularized the Systainer as the case system for its own power tools. Since then it’s expanded to hundreds of brands - a Systainer made for Festool and one made for another brand are fully compatible with each other.
Yes. The four-catch stacking design Tanos introduced with the original Systainer Classic in 1993 still works today - a Classic can stack on the bottom of a T-Loc or Systainer³. The T-Loc generation introduced a patented one-handed catch design, and T-Loc and Systainer³ stack directly on top of each other. All three generations remain part of one compatible stack.
Systainers are molded from ABS plastic and engineered to minimize weight while staying rigid. That difference is noticeable even with the case empty, before anything is loaded into it - it’s specifically what several contributors to this site point to when explaining why they switched from bulkier systems like Milwaukee PACKOUT.
Yes. Plenty of real fitouts on this site run Systainer next to other systems, including Milwaukee PACKOUT, in the same van racking. Switching to Systainer doesn’t mean giving up other storage systems you already use.
Yes. Tanos calls these brands “System Partners” - Festool, Mirka, Veritas, Mafell, and hundreds of others build their own product packaging around the Systainer. See the full list at Tanos.

Start with what you need to store and how much space you have to work with - the modular stacking system means you’re not locked into one size or configuration up front.
