Festool 577817 SYS3 S 76 TRA Systainer is a compact organizer built for storing and transporting small parts and accessories. This is a Systainer storage case designed for organizing small parts, hardware, and hand-held tools. Model Number: 577817. If you work out of a van, keep a bench organized, or need a better way to separate the little stuff that usually gets lost, this is the kind of box that earns its spot fast.

What makes this one useful is not just the size, but how that size works in the real world. The low-profile body keeps it easy to stack, slide into a rack, or carry in one hand. The transparent cover gives you a fast visual check of what is inside, which saves time when you are hunting for anchors, connectors, screws, dowels, or electrical parts. Instead of dumping everything into one bin, the included partitions let you break the interior into smaller sections that fit the way you actually work.

The interior measures 10.15 in. x 6.45 in. x 2.63 in., which is enough room for a lot of jobsite essentials without turning into another oversized case that takes up too much space. Outside dimensions are 10.43 in. x 6.73 in. x 2.79 in., so it stays compact enough for shelf storage, van storage, or keeping several organized by task. Whether you separate hardware by size, keep specialty fittings together, or dedicate one case to one install type, the format is practical and easy to manage.

Festool built this SYS3 S 76 TRA around system organization, not standalone storage. It can be combined with others of the same type and with compatible SYS-MINI units, and it is designed to work with the Systainer3 Rack for drawer-style access. That matters if you want a repeatable storage system instead of a pile of random organizers. You can build out categories by trade, by fastener type, or by phase of the job and keep the whole setup easy to transport.

Load ratings are another reason this case works better than bargain-bin organizers. It has an 11.02 lb load capacity, a 33.06 lb connected load capacity, and a permitted lid load of 220.4 lbs. In plain terms, it is made to be part of a stacked system and still hold up under real use. That does not mean it is a heavy-duty toolbox for big metal tools, but for small parts, accessories, and compact hand tools, it is built to handle normal jobsite stacking and storage pressure.

The included parts matter here too. You get four short partitions, one long partition, and a transparent cover. That gives you flexibility right out of the box instead of forcing you to buy inserts just to make the organizer usable. Festool also offers a multi-purpose insert separately if your storage needs change later. That kind of modular setup is useful if one case starts as a fastener organizer and later becomes a dedicated electrical or install kit.

This is a good fit for electricians, finish carpenters, cabinet installers, service techs, remodelers, and serious DIY users who are tired of mixed-up hardware. It is also a smart add-on for anyone already using Festool Systainer storage and wanting a cleaner way to manage the smallest items in the system. Just know the compatibility limits: it is not meant to connect to SYS 1-5, SORTAINER, or SYS MINI classic, so this makes the most sense for users staying within the compatible Systainer3 S and related mini format ecosystem.
