TSO Products Guide Rail Squares are the most refined guide rail squares available and the latest v2 evolution features drop-on compatibility so you can install it anywhere along the length of the guide rail without removing other accessories installed on the track. They are ideal for making perfectly square cuts with your track saw.

The GRS-16 PE has two reference surfaces so it can be used to align a guide rail square to the front or rear edge of the workpiece, making it more versatile. The trade-off is that there is slightly more material required to include the second reference face, so as a result, the square is slightly larger and heavier than the GRS-16.

Fits most guide rails

Compatible with Festool FS, Makita, Milwaukee and Triton guide rails.


To set up a GRS-16 Guide Rail Square, simply drop the guide rail onto it at the desired position and throw the draw latch to align it square to the guide rail and lock it in place. Then start cutting.

5-second installation

With automatic alignment and only a draw latch to install or remove the square from a guide rail, it is quick and easy to accurately set up, and just as quick to remove so there is no need to dedicate a rail to crosscutting work, or waste time setting up for crosscutting.

Compatible with track clamps

Cutouts in the square body don't interfere with the use of track clamps to secure the guide rail to your work.

Durable and lightweight

Each square is precision-machines from a single piece of 6061-T6 aluminum and anodized for a non-marking, durable finish.

Built for a lifetime of use

Thoughtfully engineered and carefully made from high-quality rust-resistant materials and components, these tools are made for a lifetime of use.

Sized to fit in a Systainer

Both GRS-16 and GRS-16 PE Guide Rail Squares fit in a single SYS1 T-Loc Systainer. Use the accessory Dual FoamPac Systainer Insert (sold separately) to keep them protected in transit.
