Right below that: Extenders, rails, and adapters in stock.
More work surface when 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 attaches directly to your machine table as an extension table and provides the workpiece with continuous support: depending on the model, it offers 77 or 104 cm of additional length, adjustable to within a millimeter using the support leg from 66 to 106 cm to ensure a flush surface.
Setup and takedown are a breeze tool-free; the extension can be attached to almost any machine and 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 for 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. This is always the first option with the Erika—the mounting adapter is only a last resort.
For RUWI ,router table , and drilling table
You can hook the table extension for mounting rail tool-free into the rail—either the short version at 77 cm or the long version at 104 cm. The mounting rail itself is a popular accessory and not included as standard equipment: once it’s bolted on, all you’ll have to do from then on is hook it in and out.
For other stationary machines
Band saw, circular 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 grips Item, Minitec, and slot-8 profiles 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 with crosscut fence extends your machine table with an anodized aluminum support 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 ly adjustable, swiveling up to 90°, and fully removable if needed. The working height can be adjusted continuously from 75.5 to 100 cm; the fold-out support leg locks into place automatically when unfolded; when used solely as a support surface, it also works with saws, planers, and jointer machines. AIGNER manufactures this safety equipment in Germany. Without a stop, it is available as a standalone AIGNER table extension. Also available: the mounting bracket for the crosscut stop and the connecting bar, which links multiple AIGNER extensions to form a continuous support.
Depending on the task, the following may also be appropriate:
Hang up and hold
Securely position and hold workpieces: the “ support rails ” set with a slip-resistant surface (tool-free , secured in the profile groove) or the clamping brackets for securing the workpieces.
Retrofit the rail
If a rail is missing from the machine: retrofit the individual mounting rail retrofit it—in 330, 430, or 530 mm for different machine widths.
For the construction site
Mobile use on the construction site: the Systainer set —extension and support rails , safely stored in an 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 strips.
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
1
support leg Unfold it and hook the extension onto the mounting rail —or attach it using the mounting adapter.
2
Adjust the height: Loosen the clamping lever , adjust it so it is flush with the table surface (66–106 cm), then close the lever.
3
Place the workpiece on the table and secure it with a support rails or quick-release clamp as needed. Done—no tools required.
Here's how the RUWI table extension
Assembly
Tool-free assembly: Unfold the support leg , adjust the height, and attach the extension—no screws required.
Height
Height continuously adjustable via the clamping lever from 66 to 106 cm, until the work surface is flush with the machine table—no edge for the workpiece to catch on.
Clamping
Clamping profile: Three slots (8 mm wide) accommodate RUWI quick-release clamps, or you can clamp directly onto the extension using clamps such as the Festool FSZ or Bessey GTR.
support rails
support rails With a slip-resistant surface: tool-free When inserted into the groove, they 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-8 profiles, such as the Festool MFT or Sauter Variobench—or screwed directly onto a band saw table, for example.
Coupling
Can be connected in any configuration: multiple extensions can be placed one after another to form a continuous support surface, or side by side for wide workpieces.
Storage
Space-saving storage: Fold up the support leg and hang it on the wall; the short Mafell version also fits inside an XXL Systainer.
Anodized aluminum base, galvanized steel mounting bracket—designed for continuous use.
table extension or a material rack?
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 Extendable Table
The RUWI table extension is an attachment table that is firmly attached to the machine and fits flush with it: 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 version for the mounting rail fits directly onto the RUWI drill press and the router table , as well as any machine equipped with a mounting rail . With the mounting adapter, the extension can be attached to many other machines and tables:
Table saws, circular saws, and panel saws; band saws; crosscut saws
Column and bench drills, row-drilling machines
Planers, thicknessers, and multi-sided planers
Edge sanders and disc sanders
Festool MFT, Sauter Variobench, Dictum multifunction table
Typical tasks: positioning long pieces of furniture and making crosscuts; cutting moldings, square lumber, and ceiling panels to length with consistent accuracy; cutting fitting strips for kitchen installations; cutting parquet planks to length for interior finishing; making miter cuts on long pieces; and supporting large workpieces on the pillar drill. The “ table extension ” is used in 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 is compatible with RUWI ,router table , and drilling table , as well as 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 Drilling 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 with the surface. This also allows it to be used with other multifunction tables or workbenches with a side slot of 8 to 10 mm.
Can I use multiple extensions at the same time?
Yes. Several can be arranged in a row to form a continuous support, or placed side by side for wide workpieces—for example, along the long side of the Mafell Erika or using two mounting adapters on the Festool MFT.
How do I adjust the height?
tool-free: Unlock the clamping lever , adjust the continuously extension to a height between 66 and 106 cm at table level, and close the lever again.
Are the mounting adapters and profile rail included in the package?
No, both are available separately. If you’re only using the Mafell Erika or—in the rail version—only the RUWI milling machine 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 do you store the " table extension "?
support leg Fold it up 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 the metal shop?
Yes, for lighter tasks such as providing additional support for a press brake, metal grinder, or drill press. It is not designed for very heavy components.
