Description

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 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-marking finish.

PRO TIP PRO TIP #1: Never use the factory edge of your material as a reference to your Guide Rail Square. For maximum accuracy, start by removing a thin slice of material to establish a perfectly straight reference edge. Learn more.

    Milwaukee guide rail square

    Posted by Zach on 9th Jul 2026

    This guide rail square is awesome. The more I use it I wish it was about half as wide as it would give me more length on my 55 inch rail when cross cutting 4x8 sheet goods. It is still a must have but using it this week I was just wishing it wasn’t as wide and it is still a must buy if you have a track saw.
