More support surface where your machine table isn't long enough.
Large or long workpieces tip over as soon as their center of gravity shifts past the edge of the table—whether you’re cutting long strips to length, trimming furniture sides, or drilling rows of holes in long cabinet sides. The RUWI table extension directly to your machine table as an add-on table and provides the workpiece with a continuous support surface: depending on the model, it offers 77 or 104 cm of additional length, adjustable to within a millimeter to be flush with the surface via the support leg 66 to 106 cm.
Setup and takedown are tool-free; the extension can be mounted on almost any machine and can be folded away or hung on the wall when not in use. If you line up several of them in a row, a short machine table turns into a continuous support surface for very long parts.

For Mafell Erika 60, 70, and 85
The table extension the Mafell Erika fits directly into the dovetail groove and can be positioned in any direction (360°)—either the short version at 77 cm or the long version at 104 cm; the short version fits into an XXL Systainer. With the Erika, this is always the first option—the mounting adapter is only a last resort.

For RUWI router table drilling table
You can clip the table extension mounting rail tool-free the rail tool-free —choose the short version at 77 cm or the long version at 104 cm. The mounting rail is a popular accessory and not included as standard equipment: once it’s screwed into place, all you have to do is clip the extension on and off as needed.

For other stationary machines
Band sliding table saw, circular sliding table saw, or sliding table saw, drill press, planer, Festool MFT, Sauter Variobench: also available in the version for mounting rail plus the mounting adapter that fits into Item, Minitec, and slot or is screwed on directly. For free lateral positioning, add the profile rail.

AIGNER with cross stop – for slot milling
When routing on a table router, support is key: The AIGNER table extension crosscut fence expands your machine table with an anodized aluminum surface measuring 1,100 × 172 mm. The crosscut fence made of beech multiplex (400 mm) defines the starting and ending points and acts as a kickback guard— continuously , swiveled up to 90°, and completely removed if necessary. The working height continuously working height continuously 75.5 to 100 cm; the fold-out support leg into place automatically when unfolded. When used solely as a support surface, it is also compatible with saws, planers, and jointer machines. AIGNER manufactures this safety equipment in Germany. Also available: the hanger for the crosscut fence and the connecting bar, which links multiple AIGNER extensions to form a continuous support surface.
To go with that, depending on the task:
Hang up and hold
Securely position and hold workpieces: the set support rails with a slip-resistant surface (securedtool-free the profile groove) or the clamping brackets for securing the workpieces.
Retrofit the rail
If a rail is missing from the machine: the single mounting rail – available in 330, 430, or 530 mm for different machine widths.
For the construction site
Mobile use on the construction site: the Systainer set —extensions and support rails in the XXL Systainer.
Short or long?
Short · 77 cm
The short version (77 cm) is sufficient for moderate overhangs—individual furniture parts, drawer sides, and shorter moldings.
Long · 104 cm
Use the long one (104 cm) when doors, stair stringers, or long solid wood panels extend well beyond the edge of the table.
If in doubt, choose the longer one or combine two extensions—too much padding never hurts, but too little does.
Assembled in three steps.
support leg and mounting rail the extension into the mounting rail —or attach it using the mounting adapter.
Adjust the height: clamping lever , adjust to table height so that it is flush with the surface (66–106 cm), then close the lever.
Place the workpiece on the table and secure it with support rails quick-release clamps if necessary. Done—no tools required.
How the RUWI table extension works
Assembly
Tool-free assembly: support leg , adjust the height, and attach the extension—no screws required.
Height
The height continuously using the clamping lever 66 to 106 cm until the support surface is flush with the machine table—no edges for the workpiece to catch on.
Clamping
Clamping profile: Three slots 8 mm wide) accommodate RUWI, or you can clamp directly onto the extension using clamps such as the Festool FSZ or Bessey GTR.
support rails
support rails a slip-resistant surface: They slot tool-free the profile groove tool-free and usually hold the workpiece in place without the need for additional clamping.
Adapter
Mounting adapter for almost any machine: for tables with Item, Minitec, or slot, such as the Festool MFT or Sauter Variobench—or screwed directly onto a band saw table, for example.
Coupling
Infinitely connectable: multiple extensions in a row for a continuous support surface, or side-by-side for wide workpieces.
Storage
Space-saving storage: support leg and hang it on the wall; the short Mafell version also fits inside an XXL Systainer.
Support made of anodized aluminum, connection made of galvanized steel – designed for continuous use.
table extension material stand?
Material Rack / Rolling Stand
A freestanding rolling stand or material stand provides localized support for long workpieces—useful for very long or heavy planks—but it sits loosely in the room and is rarely exactly at table height.
RUWI
The RUWI table extension permanently attached to the machine as an add-on table and fits flush with the surface: The workpiece glides seamlessly onto a continuous support surface, which you can also use for clamping.
For precise, repeatable cuts made directly on the machine, this is the more stable method; for occasionally supporting meter-long pieces, the material stand remains the simpler choice. The two are not mutually exclusive.
Applications and Compatibility
The mounting rail version mounting rail directly onto RUWI and router table anywhere else where a mounting rail . With the mounting adapter, the extension can be attached to many other machines and tables:
Typical tasks: positioning long pieces of furniture and cross-cuts; cutting moldings, square lumber, and ceiling panels to length with consistent accuracy; cutting fitting strips for kitchen installations; cutting parquet floorboards to length for interior finishing; making miter cuts on long pieces; and supporting large workpieces on the pillar drill. The table extension is used table extension joinery and cabinetmaking, in furniture manufacturing and the wood industry, in training workshops, and in facilities for people with disabilities.
Frequently Asked Questions About table extension
What is the difference between the two table extensions?
The Mafell version fits directly into the dovetail groove of the Erika 60, 70, and 85 and is available in short (77 cm) or long (104 cm) lengths; the short version fits into an XXL Systainer. The version for mounting rail RUWI router table drilling table any machine with mounting rail also available in 77 or 104 cm.
Which machines are compatible?
Direct: Mafell Erika 60, 70, and 85, as well as RUWI and router table. With the mounting adapter, it is also compatible with table saws, circular saws, and format saws; band saws and miter saws; drill presses, bench drills, and row-hole drills; planers, thicknessers, and multi-sided planers; edge sanders and disc sanders; as well as the Festool MFT and Sauter Variobench.
Does the extension fit the Festool MFT?
Yes, using the mounting adapter, which is sold separately. It connects securely to the outer profile and can be adjusted vertically using the slotted hole, so that the extension fits flush. This means it also fits other multifunction tables or workbenches with a side slot 8 to 10 mm.
Can I use multiple extensions at the same time?
Yes. You can line up several to create a continuous support surface or place them side-by-side for wide workpieces – for example, along the long side of the Mafell Erika or with two mounting adapters on the Festool MFT.
How do I adjust the height?
tool-free: clamping lever , adjust the extension continuously 66 and 106 cm at table height, and close the lever again.
Are mounting adapters and the profile rail included?
No, both are available separately. If drilling table only on the Mafell Erika or—in the rail version—only on drilling table RUWI and drilling table , you don’t need an adapter. It’s required for other stationary machines; the profile rail complements it for more flexible lateral positioning.
How is the table extension ?
support leg and hang it on the wall using the built-in hanger. The short extensions (77 cm) fit into an XXL Systainer—either individually or as part of a Systainer set.
Can the extension also be used in a metal workshop?
Yes, for lighter tasks like providing extra support for a press brake, metal grinding machine, or pillar drill. It's not designed for very heavy components.
