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.
