About this product
Key Features
Overview
The Festool SYS3-MFT M 112 Systainer, Model Number 578496, is a portable workbench and storage case built for small-part clamping, fitting, and support work on the jobsite. This is a portable workbench designed for securing workpieces during trim work, laminate work, sanding, drilling, and other quick adjustments away from a full bench. If you already work out of the Festool storage system, this gives you a real working surface without giving up portability.
What matters here is not just that it stores tools. The lid is an MDF perforated top with 13/16" (20 mm) holes, a center handle groove, and a V-groove layout that helps hold different shapes. That setup lets you clamp down flat parts, small trim pieces, and even round rods or pipes up to 2 in. diameter. Festool also builds in a foam strip so material can sit with extra grip even when you are not clamping it down. For quick fitting work, that saves time.
The size is compact enough to stay useful instead of becoming another bulky box. Overall dimensions are 15-1/2 in. x 11-1/2 in. x 4-1/2 in., with inside dimensions of 15.31 in. x 10.83 in. x 2.80 in.. At 4.4 lbs, it is light enough to carry one-handed, but the lid is rated for serious support with a 220 lb lid load capacity. The main case load capacity is 44 lbs, and connected load capacity is 88 lbs, so it is built to do real work, not just hold accessories.
Jobsite practicality is where this setup makes sense. Instead of dragging a stand or finding floor space for a larger bench, you can set the Systainer down on a table, bench, or stable surface and start working. That is especially useful for installers dealing with trim, baseboards, laminate flooring, profile strips, and hardware fitting where the work is light but precision still matters. It is also handy when you need support close to a miter saw or assembly area.
The Festool SYS3-MFT M 112 Systainer also fits into the broader Festool storage and clamping ecosystem. It is compatible with Festool MFT clamps and accessories, connects with Festool Systainers, and it is also compatible with T-LOC, Classic Systainers, and Sortainers. Festool also notes that a second same-height Systainer can be used as added support for longer stock, which turns this compact unit into part of a larger workflow instead of a one-off accessory.
Who should buy it? Finish carpenters, flooring installers, remodelers, cabinet installers, and serious DIY users will get the most out of it. If your work involves lots of small cuts, fitting, light sanding, drilling, or holding awkward pieces in place while you mark or adjust, this is a smart addition. If you need a full-size bench for sheet goods or heavy fabrication, this is not that. But for mobile finishing work and quick fixes, it is exactly the kind of thing that earns a permanent spot in the van.
Carry a Bench to the Work
If you do punch work, trim fitting, or small installs, the biggest advantage here is simple: you get a stable work surface without dragging a full bench into the space.
- Lightweight at 4.4 lbs for easy one-handed carry
- Combines storage and work surface in one unit
- Same-height support can be added with another matching Systainer for longer pieces
Secure Small Parts Without Fighting Them
The top is designed to hold real workpieces, not just look clever in the catalog. Flat stock, trim, pipes, and rods can all be steadied in different ways depending on the job.
- MDF perforated top accepts MFT clamps and accessories
- Foam strip helps keep material from sliding when you are positioning or marking
- V-groove supports round rods and pipes up to 2 in. diameter
Useful Support for Long, Awkward Stock
For long trim, dowels, and pipe, the shape of the top matters. The groove and clamping layout give you a controlled place to hold stock while you mark, fit, or make small adjustments.
- Hole pattern uses 3/4 in. diameter openings in the MDF board
- Lid load capacity is rated at 220 lbs
- Good fit for trim, profile strips, laminate work, and round stock support

Pro Tip
If you are fitting long trim or narrow stock, pair this with another same-height Systainer beside it. That gives you a simple infeed or outfeed support without hauling a separate stand.

Tool Nut's Take
Festool SYS3-MFT M 112 Systainer is the kind of accessory that makes mobile work easier
This is a smart buy for anyone who works out of Systainers and needs a fast, compact clamping surface instead of improvising on a floor, tailgate, or pile of cutoffs.
- Who it's for: Trim carpenters, flooring installers, remodelers, cabinet installers, and organized DIY users doing small-part work on site.
- Why it stands out: It is not just a box. You get storage, a perforated MDF top, a V-groove for round material, and real system compatibility in one portable piece.
- Worth knowing: This is best for light machining, fitting, and support work. If you need a full-size bench for sheet goods or heavy assembly, step up to a larger table.
