Key Features
Repeatable Angle CutsThe connectible cross-cutting rail system is built for fast, guided cross cuts with repeat accuracy. If you are knocking out the same angle over and over, the stop system and locking positions help you get there quicker with less setup fuss. Wide Miter RangeWith an angular range from -45 degrees to +60 degrees, this guide rail gives you the flexibility to handle common trim and framing angles without switching to a different setup. Automatic ReturnThe integrated rubber spring brings the saw back to the start position after the cut. That speeds up repetitive work and keeps the Festool 769941 FSK 250 Cross Cutting Guide Rail feeling controlled instead of awkward between cuts.
Overview
The Festool 769941 FSK 250 Cross Cutting Guide Rail is a guide rail accessory made for quick, accurate cross cuts with compatible Festool saws. This is a cross-cutting guide rail designed for repeatable angled cross cuts on workpieces where speed and consistency matter. Model Number: 769941. If you already run an HKC 55, HK 55, TS 60 K, or TSV 60 K, this accessory turns that saw into a more controlled cross-cutting setup for shop work, trim work, and jobsite cuts.
The big story here is repeatability. Festool built this rail with an adjustable stop, preset locking positions for common angles, and a connectible design that lets the saw and rail work as one unit. That matters when you are making the same cut again and again and do not want to fight layout drift, freehand error, or a clumsy straightedge setup. The 9-7/8 inch cutting length is sized for shorter cross cuts, and the -45 to +60 degree angular range gives you useful flexibility for miter work.
The integrated rubber spring is one of those features that sounds small until you use it. After the cut, the saw returns to the starting position automatically. On repetitive cuts, that keeps the process moving and makes the setup feel more like a purpose-built cross-cut station than a basic rail. Festool also calls out slideway lining for easier movement and a quick fastener system that connects the saw to the rail cleanly, which helps the whole assembly stay predictable through the cut.
Workpiece protection is also part of the design. The splinter guard helps support cleaner cut edges, while the adhesive cushion strip helps protect the material surface during setup and cutting. Add the included screw clamp, which attaches into the rail groove, and you get a more secure hold on the workpiece without improvising with separate clamps that may get in the way.
For real-world use, this accessory makes the most sense for finish carpenters, remodelers, installers, and woodworkers who want guided cross cuts without dragging out a larger stationary saw. It is especially useful when the material is already in place, the cut list is repetitive, or space is tight and portability matters. At about 2.16 to 2.2 pounds, it is light enough to carry with the saw instead of treating it like a shop-only accessory.
Compatibility is important with this product. Official Festool fitment lists the FSK 250 for the HKC 55, HK 55, TS 60 K, and TSV 60 K. If you are shopping for a rail to use with a plunge saw outside that fitment, this is not the place to guess. The value of this system comes from the matched saw-and-rail setup, so buy it when you want that exact Festool cross-cutting workflow rather than a generic guide rail.
If your work is mostly short, accurate cross cuts and angled cuts with a portable saw, this rail earns its keep. If you need long rip cuts, this is not the accessory you buy first. The Festool 769941 FSK 250 Cross Cutting Guide Rail is for users who want fast setup, dependable angle control, and cleaner, more repeatable cross cuts from a compatible Festool platform.

- Connectible rail system for guided cross cuts with repeat accuracy
- Adjustable stop system helps dial in repeated angled cuts
- 9-7/8 inch cutting length is sized for short, controlled cross-cut work
Lock In Common Angles Quickly
The angle scale and locking positions are there to save time, not just add numbers to the rail. When you move between standard cut angles during trim or install work, quick indexing helps you stay productive.

Pro Tip
If you are batch-cutting the same part, set the stop once and use the rail’s locking angle positions instead of remeasuring every piece. Pair that with the included clamp in the rail groove and the setup stays faster and more consistent from the first cut to the last.
