How much does the Systainer3 XXL 337 hold?

It has 17 gal (64.2 liters) of interior volume, the largest in the Systainer3 line. That fits large tools, accessories or a mix of loose jobsite gear.

How much weight can it take?

Festool rates it at 88.18 lb carried, 176.37 lb when connected to other Systainers, and 220.46 lb on the lid. Those figures cover transport and stacking, not just storage.

Does it connect to other Systainers?

Yes. The T-LOC latch connects it to other Systainer3 cases with one turn, so it can sit at the bottom of a stack. It also works with older Systainer generations that use T-LOC.

Is it the same as the smaller Systainer3 cases?

It uses the same T-LOC system and footprint family, but the XXL 337 is much taller and wider inside. Choose it when you need volume, not for small parts.

Does it come with dividers or an insert?

The case is sold as the container itself. Internal dividers and tool inserts are separate accessories, so plan for them if you want organized small items.

Shoppers who don't already use Systainers get little from the stacking system. For light home storage, a simpler tote does the same job with less bulk.

Our take on the Festool Systainer3 XXL 337 (204851)

The Systainer3 XXL 337 is Festool's largest stackable tool case, with 17 gal (64.2 liters) of interior volume for big tools, accessories and loose jobsite gear. It uses the T-LOC single-latch system, so it opens, closes and connects to other Systainers with one turn. It is rated for 88 lb carried, 176 lb when connected in a stack and 220 lb on the lid, which is what separates it from a plain plastic tote. It suits tradespeople already in the Systainer ecosystem who want one large case instead of several small ones; anyone outside that system gets less from it.

About the Festool Systainer3 XXL 337 (204851)

The Festool Systainer3 XXL 337 (model 204851) is a large-format tool storage case for transporting and organizing machines, hand tools, accessories, small parts and other equipment. It holds 17 gal (64.2 liters) and has a long, low shape for bulky tools and longer accessories.

It is part of Festool's Systainer platform. The T-LOC operating element opens, closes and connects the case in one motion, so it stacks with other Systainer3 and Systainer T-LOC cases without separate latches or stack clips. The case can be secured with straps for vehicle transport.

An integrated latch keeps the contents secure. A recessed grip and a pull-out aid make it easier to handle, and a label field lets you mark what is inside. This version comes without a tool insert, so the interior is open storage. The Systainer3 platform protects against dust and spray water.
