The Festool 577157 Guide Rail Accessory Kit w/ Systainer3 is a guide rail accessory kit built to expand what you can do with Festool FS/2 guide rails. This is a guide rail accessory kit designed for more accurate cutting, cleaner routing, and better jobsite organization. Model number 577157. If you already rely on a Festool guide rail for track saw or router work, this set gives you the accessories that make setup faster, cuts more repeatable, and transport a lot less messy.

What makes this kit useful is that it brings together the accessories most users end up wanting anyway: an FS-WA angle stop, FS-RSP limit stop, FS/2-AW deflector, (2) FSV/2 guide rail connectors, and (2) FSZ 120 screw clamps, plus the combination hex key and a SYS3 M 137 Systainer to keep everything together. Instead of buying pieces one at a time and tossing them in separate boxes or drawers, you get one organized kit that stays ready to go.

On the job, those accessories solve real problems. The angle stop quickly attaches to the guide rail without tools and lets you set angles from -60° to +60°, which is a big deal for repeatable angled cuts and layout work. The rail connectors let you align and join two guide rails with more confidence when you need a longer cutting path. The fastening clamps help secure the workpiece so the rail stays where it belongs instead of shifting when you lean into the saw or router.

The limit stop is one of those parts that sounds small until you use it. It can act as a start and stop reference, and Festool also calls out its role in helping protect the circular saw user against kickback when plunging into the workpiece. For anyone doing repeated plunge cuts, grooves, or controlled entry points, that added reference makes the setup more predictable and easier to trust.

The deflector is another practical upgrade. It helps prevent the suction hose and power cord from hanging up on the end of the guide rail, which keeps movement smoother through the cut. If you run a dust extractor with your saw or router, that matters more than it sounds. Snagged hoses slow you down, throw off your rhythm, and can affect the quality of the cut.

Festool also did the smart thing by packing everything into a Systainer instead of treating storage like an afterthought. The accessories are stored in a clearly organized layout inside the SYS3 M 137, so you can see what is there, spot what is missing, and move the whole kit as one unit. That matters for shop organization, van storage, and keeping small rail parts from disappearing between jobs.

Compatibility is straightforward. This set is listed as suitable for FS/2, so it is intended to work within Festool's FS/2 guide rail system. It is a strong fit for woodworkers, cabinet installers, finish carpenters, remodelers, and serious DIY users who already own Festool guide rails and want more control over straight cuts, angled cuts, and guide rail handling.

If you use a guide rail only once in a while, this may feel like a convenience upgrade. If you use one regularly, it is more than that. The right stops, clamps, and connectors cut down setup time, improve consistency, and make the whole rail system easier to live with day to day.
