Safety system for a sliding table saw

Your hands and fingers are your most important tools

Press, turn, secure: With the RUWI and sawing system, you can sliding table saw workpieces of any shape and size to the sliding table saw table of your sliding table saw — tool-free in about 10 seconds. Your hands stay out of the danger zone, even when working with small, narrow, or angled pieces.

At a glance: tool-free and set up in about 10 seconds; securely holds workpieces of any shape on the sliding carriage; tested by the German Social Accident Insurance Association (BGHM) and awarded the DGUV seal of approval—for upright, back-friendly work.

Classic or Premium?

Both versions safely cut small, narrow, and angled workpieces and fit standard sliding table saws. The difference lies in trimming long workpieces: To do this, you clamp the board at the front and back—which is what the premium version does with its second swivel clamp the two narrow auxiliary stops with holding tips.

Both versions are compatible with machines from Altendorf, Martin, Felder, and other manufacturers upon request. You can upgrade a Classic Set to the Premium package at any time—using a second swivel clamp and the two narrow auxiliary stops (available upon request).

An alternative to the “Fritz and Franz” sawing aid

Many woodworkers are familiar with the “Fritz und Franz” sawing aid—developed by the employers’ liability insurance association—which ensures safe sawing of small workpieces. It’s a proven and affordable solution. The RUWI and sawing system takes it two steps further: You can secure the workpiece tool-free onto the sliding carriage—without an additional crosscut fence—and can also clamp it at an angle, which makes all the difference when making miter and wedge cuts. For cutting small parts only, “Fritz und Franz” remains the simple choice; but if you regularly need to cut angled, long, or warped workpieces safely, the RUWI offers a more convenient solution.

Workplace Safety That Doesn't Take Any Time

In everyday workshop life, there’s often little time for workplace safety—even though it’s crucial to your health. The RUWI takes the guesswork out of it: slot the clamping cylinder into the slot from above, rotate it 90°, and clamp it in place—in about 10 seconds, the workpiece is secured, and you’re complying with BGHM recommendations with minimal effort. The clamping cylinders and pressure plates adjust to accommodate large, small, and complex-shaped parts, so you can work safely even without a second person. Because you stand upright and apply the clamping force the ergonomic handle, this system is easy on your back during long cutting runs. The included wall panel the saw keeps all components within easy reach.

Trimming Solid Wood

When trimming boards or planks, you mount a clamping cylinder with a swivel arm on the front of the sliding carriage and secure the board; at the rear, the feed stop presses against the end face. With the Premium Set, you mount one clamping cylinder with a swivel arm at the front and one at the rear, and place the two narrow auxiliary stops in between—the retaining tips prevent the workpiece from slipping.

Sawing Small Parts Safely

There's no need to hold small workpieces by hand close to the saw blade. Place the auxiliary stop on the sliding carriage, adjust the angle and distance from the saw blade, and secure it firmly to the carriage using the swivel arm. Then insert the feed stop into the slot, align it, and secure it with the clamping lever.

Slopes and Angles

Using the flexible feed stop and the angled auxiliary stop, you can position workpieces at any desired angle. The clamping cylinder and pressure plate accommodate a wide variety of workpiece sizes—allowing you to make miter cuts and wedge cuts with confidence.

The wall panel made of powder-coated steel holds all components next to the saw. The angled auxiliary stop is adjustable in angle and distance via a slotted hole, and its rubber edge slipping. The two narrow auxiliary stops in the Premium Set are secured tool-free the clamping cylinders tool-free ; their screw-in retaining tips provide additional support when trimming long workpieces.
