The Festool 491499 32" Guide Rail FS 800 is a guide rail built for straight, controlled cuts and guided tool movement. This is a guide rail designed for precision cutting and routing with compatible Festool tools. Model Number 491499. If you are working with a Festool plunge-cut saw and need a shorter rail for trim parts, narrow panels, or smaller bench work, this 800 mm rail gives you the same cut-line accuracy as the longer FS rails in a more compact size.

The big reason to use a rail like this is repeatable accuracy without the usual layout headache. Festool rates the FS 800 for precision cuts up to 26 inches long when used with a Festool TS plunge-cut saw. The integrated splinterguard acts as your cut line, so you can place the rail where you want the cut and get to work without second-guessing offset measurements. That saves time on cabinet parts, finish pieces, and sheet stock breakdown where being off even a little means wasted material.

Festool also built this rail around clean edge quality. The splinterguard is there to help reduce tear-out and splintering on cuts with the grain and across it. On real jobs, that matters because cleaner edges mean less sanding, less cleanup, and fewer do-overs. For finish carpentry, cabinetry, and shop work, that is one of the biggest reasons people buy into the Festool guide rail system in the first place.

From a handling standpoint, the non-skid dual-clamping rubber strips are a practical feature, not a gimmick. They help the rail stay put during cutting, which cuts down on setup time and makes the tool feel more controlled from the start of the cut through the exit. Festool also notes that the guide strip reduces friction between the tool and guide rail, which helps the saw or router move more smoothly along the track.

This rail is not limited to track saw work. It is part of the broader Festool guide system, so you can use compatible Festool routers or jigsaws on the same rail for guided cuts and repeatable straight-line work. If you need more length later, Festool guide rails can be connected with guide rail connectors to create a rigid, continuous rail for longer cuts. That makes the FS 800 a useful starter rail, a dedicated short rail for shop use, or an add-on to a larger rail setup.

At 32 inches long and about 2.9 lbs, this is an easy rail to store, carry, and set up when a full-length rail would just get in the way. It is especially well suited to woodworkers, cabinet installers, remodelers, and trim carpenters who need portable straight-line accuracy without dragging larger shop equipment to the job. If most of your work involves smaller panels, narrow stock, or quick accurate crosscuts with a Festool system tool, this size makes a lot of sense.
