Safety System for Panel Saws

Your hands and fingers are your most important tools

Press, turn, secure: With the RUWI clamping and sawing system, you can securely clamp workpieces of any shape and size onto the sliding table of your panel saw—without tools and 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 operation 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 working.

Classic or Premium?

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

Both versions are compatible with machines from Altendorf, Martin, Felder, and other manufacturers upon request. A Classic set can be upgraded to a Premium set at any time by adding a second swivel clamp.

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 is a proven and affordable solution. The RUWI clamping and sawing system takes it two steps further: You secure the workpiece directly onto the sliding carriage without tools—no additional crosscut fence required—and can also clamp it at an angle, which makes all the difference for miter and bevel cuts. For simple small-part cuts, “Fritz und Franz” remains the easy choice; but if you regularly need to safely cut angled, long, or warped workpieces, the RUWI system offers a more comfortable experience.

Workplace safety that doesn't take up any time

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

Applications and Compatibility

The RUWI safety system is a workplace safety solution for standard sliding table saws. Using the swivel clamp, you can install it on machines from Altendorf, Martin, Felder, and other manufacturers. It is used in carpentry and joinery shops, in the woodworking industry and furniture manufacturing, by professional DIYers and woodworkers, in training workshops, and in facilities for people with disabilities.

Compatible with Altendorf, Martin, Felder (X-Roll, Format 4, Hammer), Panhans, SCM, Holzkraft / Minimax, and other panel saws with a sliding table or push table—just contact us.

How to use the system

The system comes pre-assembled and can be set up on the saw without tools: Insert the clamping cylinder with the slotted nut into the slot, rotate it 90°, and clamp it in place. The feed stop has a long slotted nut that fits the slot width of your machine.

Trimming solid wood

When trimming boards or planks, 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, mount a clamping cylinder with a swivel arm at both the front and rear and position the two narrow auxiliary stops between them—the retaining tips prevent the workpiece from slipping.

Sawing small parts safely

There’s no need to hold small workpieces close to the saw blade by hand. 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 groove, align it, and secure it with the clamping lever.

Slopes and Angles

The flexible feed stop and the angled auxiliary stop allow you to position workpieces at any desired angle. The clamping cylinder and pressure plate accommodate a wide range of workpiece sizes, enabling you to make miter cuts and bevel cuts with confidence.

Clamping long workpieces directly on the sliding carriage (Premium)

With the premium version, you can clamp long workpieces directly onto the sliding carriage. The second swivel clamp and the narrow auxiliary stop secure the board at two points—you can rotate and tighten it until the cut is just right, even with warped boards.

The individual components: The clamping cylinder can be attached anywhere along the groove without tools and, thanks to its long travel, can also be mounted at an angle or in combination with other components. The feed stop holds the workpiece against the auxiliary stop while keeping your fingers out of the danger zone; you adjust the distance and angle to the saw blade using the clamping lever. The pressure plate adapts to the shape and size of the workpiece via a ball joint and rubber pad—even on uneven parts, without damaging the surface. The swivel arm is attached to the clamping cylinder, rotates 360°, and secures the workpiece via the ergonomic handle. 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 prevents slipping. The two narrow auxiliary stops in the Premium Set are secured to the clamping cylinders without tools; their screw-in retaining tips provide additional support when trimming long workpieces.
