The Festool SYS3-RACK/6 M 337-SET Systainer Set, model 577816, is a modular storage rack built to organize and transport small Systainers in one stackable unit. This is a Systainer rack designed for storage, organization, and transport of MINI-Systainer S 76 cases. If you keep fasteners, fittings, install hardware, blades, bits, or layout parts separated by task, this setup gives you a cleaner way to move them from the shop to the jobsite without losing the system advantage of Festool Systainers.

What makes this setup useful is the format. Instead of six loose mini cases floating around the truck or workbench, the rack holds them in a shelf-style frame with front access. That means you can grab the case you need without unstacking everything above it. Festool also builds in a spring-assisted removal setup, so taking a MINI-Systainer out is quick and deliberate instead of awkward. For trades that burn time hunting for connectors, anchors, screws, and small install parts, that alone is a real benefit.

The rack is sized at 15.59 in. long by 11.65 in. wide by 12.99 in. high and weighs 18.51 lbs. In practical terms, it is compact enough to live on a shelf, bench, van floor, or in a larger Systainer stack without becoming bulky. The load capacity is 44.09 lbs, with 88.1 lbs load capacity when connected and a permitted lid load of 220.4 lbs. That matters because this is not just a plastic organizer for light bench duty. It is built to work as part of a real transport system where stacking strength counts.

Festool designed the SYS3-RACK/6 M 337-SET around the broader Systainer platform, which is the whole point of buying it instead of a generic drawer box. It is compatible with the Festool Systainer system and works with all Systainer generations, mobile dust extractors, and many other system accessories. It is also suitable for all Systainer3 S 76 versions and transport and storage of SYS-MINI 1 T-LOC, while specifically not being suitable for Systainer3 S 147. If your shop is already built around Systainers, this rack keeps your small-part storage in the same workflow.

On the job, the big advantage is organization without giving up mobility. Festool calls out use with the SYS-RB roll board and SYS-Roll handtruck, which makes sense because a loaded rack of small parts is most useful when you can move it with the rest of your stack. This is especially handy for installers, finish carpenters, service techs, cabinet crews, electricians, and punch-list work where the right small item needs to be there when you need it, not back in the van.

The included six Systainer3 SYS3 S 76 mini cases turn the rack into a ready-to-use kit instead of an empty shell. That is a better buy for anyone starting a parts organization setup because you can dedicate cases by category right away. One for electrical connectors, one for cabinet hardware, one for anchors, one for blades, one for specialty fasteners, one for consumables. You get the same footprint, better separation, and a much cleaner system.

Who should buy this? Anyone already invested in Festool storage who wants a better answer for small parts than loose mini boxes. It is also a smart fit for organized pros who work out of a van or trailer and need quick front access to sorted supplies. If you do not use Systainers at all, the value is in the system compatibility. If you do, this is one of the cleaner ways to keep the small stuff under control.
