Sale price$428.95


The GRS-16 Guide Rail Squares are the most refined guide rail squares available. They are ideal for making perfectly square cuts with your track saw.

Fits most guide rails

Compatible with Festool FS, Makita and Triton guide rails.


To set up a GRS-16 Guide Rail Square, simply slide it onto your guide rail to 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.

GRS-16 versus GRS-16 PE

The GRS-16 has one square reference face and is suitable for aligning a guide rail square to the front edge of the workpiece. It is the smaller and lighter version.

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.

Combination Set includes one of each.
