Systainer3 StorageThe Festool abrasive storage Systainer gives you moisture-protected transport and cleaner organization on the truck, in the shop, or at the jobsite. T-LOC SystemOpen, close, and connect with one turn. That matters when this case is stacked with other Systainers and you do not want to break down the whole pile to reach your sanding discs.
Overview
The Festool 576781 Systainer3 for LS 130, RTS 400, DTS 400 and 125mm Abrasives is a dedicated storage case built to organize sanding abrasives by shape and size instead of leaving them loose in drawers or half-open boxes. This is a Systainer designed for storing and organizing abrasives for finish sanding and surface prep. Model Number: 576781. If you use multiple sanding formats and grit ranges through the day, this case makes setup faster and keeps your abrasive stock protected from moisture and damage.
What sets this one apart is the insert. It is built for abrasives measuring 80 x 133 mm, 125 mm diameter, and Delta format, which covers common paper used with Festool LS 130, RTS 400, DTS 400, and 125 mm sanders. Instead of stacking different sheets together and guessing what is left, the five-compartment layout gives you a clear visual count and a cleaner system for separating grits, fresh discs, and partially used paper you still want to keep.
The practical benefit is simple: less wasted abrasive and less wasted motion. When sheets stay flat, separated, and easy to identify, abrasive changes happen quicker and you are less likely to toss usable paper because it got bent, mixed, or contaminated. For guys doing finish work, cabinet installs, punch-list sanding, or shop prep, that kind of organization matters more than it sounds. Sanding is already one of the slower parts of the job. Hunting for the right grit should not make it worse.
Festool built this around the T-LOC concept, which is the central latch system used across its Systainer lineup. One turn lets you open, close, and connect the case. The real-world advantage is that you can open the Systainer without disconnecting it from the other stacked Systainers first. If your setup lives in a van, trailer, or rolling shop system, that is a legitimate time-saver, not just a nice extra.
In terms of size, this is a SYS3 M 112 case with overall dimensions of 15.59 x 11.65 x 4.40 inches. That gives you enough internal volume for organized abrasive storage without taking up the footprint of a larger toolbox. At about 3.8 lbs, it is light enough to carry one-handed but still substantial enough to hold up as part of a stacked transport system.
Compatibility is a big part of why this product makes sense for existing Festool users. It is designed to connect with all Systainer generations, mobile dust extractors, and other system accessories. So this is not just a plastic box for sanding discs. It is part of a transport and organization platform that helps keep sanders, abrasives, and dust collection working together in one kit.
Who should buy it? Anyone already invested in Festool sanders who is tired of loose abrasives getting bent, damp, dusty, or mixed together. It is especially useful for finish carpenters, painters, remodelers, cabinet installers, and serious DIY users who keep multiple grit progressions on hand. If you only use one paper size once in a while, you can get by without it. If sanding is routine work, this case keeps the consumables side of the system just as organized as the tool side.

Pro Tip
Set each compartment up by grit progression instead of by abrasive shape alone. If you run through 80, 120, 150, and 220 during the same sanding sequence, that layout makes paper changes quicker and helps you spot low stock before a job starts.
