Square Cuts Made Fast and Easy with Your Track Saw
Breaking down sheet goods is easy with a TSO Guide Rail Square in your shop. This must-have track saw accessory turns your guide rail into a large, precision square, enabling fast and accurate 90-degree crosscuts with less setup time, less marking, and fewer errors.
The GRS-16 PE v2 Guide Rail Square is perfect for crosscuts on sheet goods and is compatible with Festool, Makita, Milwaukee, Powertec, Triton, and WEN track saw systems.
Key Features
- Born Square: A proven design, CNC-machined from a single block of 6061-T6 aluminum, will never require fine-tuning or calibration.
- Work Faster: No need to scribe your cutting line; make a small tick mark at your desired cutting position, align the guide rail, and you're ready to start cutting.
- Fewer Errors: Cut your marking and measuring in half, and with it, your chances of making a mistake that costs you valuable time and materials.
- Parallel Edge: Reference your work from the front or back edge to fit your workflow.
- Solid Connection: A resilient latch coating grasps the guide rail and protects it from damage.
- Drop-on Convenience: Quickly attaches without the need to remove accessories, like hose deflectors, track connectors and clamps.
- Clamp Compatible: Notches on both reference edges provide room for your favorite track clamp. Including the Festool Screw Clamp (489570), Ratcheting Clamp (491594), and Axminster guide rail clamps.
- System Approach: Compatible with the TSO Parallel Guide System for making repeatable square and parallel cuts in one workflow.
- Anodized Blue: Provides a beautiful, durable, and non-marring finish.
- Made in the USA: Designed, manufactured and hand-assembled in Eagan, Minnesota.

Not Square
I wanted to like this guide rail square. But unfortunately after hours of testing and back and forth with customer service I have never gotten a 90 degree cut. I have tested the guide rail square on several different tracks (makita and festool) and every time the cut is consistently out of square. I have checked the guide rail square with my woodpeckers 1282 square and when attached it does not sit at 90 degrees. Again, I have tested this many times and on several different tracks all with the same result. Ultimately customer service told me "we should cut our losses". I see so many people online using these guide rail squares so I wanted to trust this would be a reliable add on for my track saw. The fit and finish is great and it's easy enough to attach but if I cannot rely on the guide rail square for a 90 degree cut then those features don't matter.

GRS-16 PE V2
It works!!! it’s simple and it works. I’ve seen a bunch of YouTube videos demonstrating how you can take a completely out of square piece of material and make it square. First use made a shelf for a cabinet I’m building and all four corners are dead square. This was money well spent. I will now have a lot less wasted material trying to get plywood square and ready for the table saw. Also the customer service is excellent and very helpful.
