Smart clamping tools designed specifically for 20-mm-hole grid
Clamping on the 20-mm-hole grid
All clamping tools here attach directly to the hole grid of your table via a clamping bolt Ø 20 mm bolt—on the RUWI router table , the lifting table, the table extension , or the Festool MFT. You insert the tool into the hole, tighten the bolt, and it’s securely held in exactly the position your workpiece needs. Because the bolt is the same everywhere, each part can be moved freely between your tables.
Which tensioner is right for which task?
- Press the workpiece down onto the table from above: vertical toggle clamp – holds flat parts in place during drilling, milling, or grinding.
- Clamp the workpiece sideways against a stop: horizontal toggle clamp – Press horizontally, for example, against a stop edge.
- Fast and repeatable clamping: eccentric clamp – secured with a lever mechanism, for repetitive clamping in a production line.
- Position freely with a large " clamping range": the Bessey TW 16 screw clamp with adapter disc or the Bessey GTR 160/60 bench clamp.
- Aligning and positioning workpieces: positioning angle and clamping brackets with clamping lever provide a solid stop edge.
- Securely support long workpieces: support rails and the set with anti-slip coating keeps the material securely in place.
Comparison of Clamping Directions and Compensation
How the three RUWI clamps differ technically—and why the automatic compensation feature makes a difference in everyday use: They clamp workpieces of varying thicknesses without requiring you to readjust the pressure spindle each time.
| Tensioner | Clamping Direction | Automatic compensation for varying thicknesses |
|---|---|---|
| vertical toggle clamp | from above onto the table | 35 mm (height adjustment up to 40 mm) |
| horizontal toggle clamp | horizontally against a stop | 13 mm (stroke compensation –35 mm) |
| eccentric clamp | by lever (eccentric) | – (quick re-clamping) |
The vertical toggle clamp is a toggle-type clamp with a pressure spindle and—like the horizontal toggle clamp —automatically compensates for varying workpiece thicknesses; the eccentric clamp clamps using a lever without a spindle, making it faster for repeated use. All three are mounted on the clamping bolt (Ø 20 mm) at any grid position.
If you only need the connection to the hole grid, you can also find the individual clamping bolt with a screw or the clamping bolt with a washer sold separately—for example, to build your own assemblies.
The Fastest Way to Get Started: The Premium Set
If you don't want to put together a set piece by piece, go with the Premium Clamping System Set for hole grid Ø 20 mm. It bundles the most important clamps and clamping bolt into one set—the straightforward basic kit that lets you get started right away and add specific items later.
Can be combined with any tool
The system is intentionally open: In addition to the RUWI clamps, Bessey clamps also work with the clamping bolt, and the tools fit any table with a 20-mm grid—not just RUWI tables, but also the Festool MFT. You can find compatible stop accessories in the adapters and stops section.
Frequently Asked Questions
Do I need tools to tighten it?
Tighten the clamping bolt from above using a SW 6 Allen wrench—this secures the clamp firmly in the hole grid. The clamping process itself is then quick and easy using the lever or pressure spindle.
What table thickness does the clamping bolt require?
The clamping bolt is suitable for tables with a wood thickness of at least 16 mm and for metal with a thickness of at least 4 mm. Thinner panels cannot securely hold the bolt.
What is the automatic balancing function for?
It clamps workpieces of varying thicknesses without requiring you to readjust the clamping spindle each time—up to 35 mm on the vertical toggle clamp , and up to 13 mm on the horizontal toggle clamp . This saves time when switching between parts.
