The Festool 204847 Systainer3 L 187 is a modular storage case built for transporting tools, accessories, and consumables between the workshop, vehicle, and jobsite. This is a storage case designed for organized tool transport and system-based jobsite storage. Model Number 204847. If you already work in the Festool system, this case matters because it gives you a wider footprint and useful internal volume without giving up the stacking and connection features that make Systainers practical in the first place.

The big advantage here is capacity and organization. Festool lists a 5.34 gallon volume, with internal dimensions of 19.72 inches long x 10.83 inches wide x 5.67 inches high. That gives you enough room for larger accessories, layout gear, abrasives, hand tools, or mixed supplies that do not fit as cleanly in smaller cases. The wider base area is the point of this model. It gives you more usable packing space, not just more outside bulk.

Festool also kept the T-LOC operating system, which is still one of the better features in the Systainer platform. You can open the case, close it, or connect it to another compatible Systainer with a single turn. On the job, that means less messing around when you need one case out of a stack or want to lock multiple cases together for transport. The front handle also keeps the carry position close to the body, which is a lot more comfortable when the case is loaded down.

For real-world transport, the weight and load ratings matter. The case itself weighs 4.63 pounds, so it is not heavy before you fill it. Festool rates it for a 44.09 pound load capacity, 88.18 pounds when connected, and 220.46 pounds of lid load. That gives you a clear idea of what it can handle in a stacked storage setup, in a van, or on a crowded site where cases get used as temporary work surfaces and staging points.

This Systainer3 is sold without a tool insert, which is actually useful if you want flexibility. Instead of being locked into one molded layout, you can set it up around the tools or supplies you actually carry. For contractors who change setups from one job to the next, that is often the smarter option. It is also easier to dedicate a case to task-specific kits like finish hardware, measuring tools, sanding supplies, or installation accessories.

Compatibility is another strong point. Festool states that Systainer3 products connect with one another, with previous Systainer generations, with mobile dust extractors, and with other system accessories. The platform was also developed with vehicle integration in mind, which makes it a solid fit for organized van setups where secure transport and fast access matter. If your workflow depends on keeping gear sorted and movable, that system approach is the reason to buy this case instead of a generic toolbox.

The Festool 204847 Systainer3 L 187 makes the most sense for carpenters, installers, remodelers, service techs, and serious DIY users who already value organized storage and modular transport. If you just need a cheap bin, this is more case than you need. If you want a stackable, durable storage solution that works with the rest of the Festool ecosystem and keeps your gear organized from shop to site, this one earns its place fast.
