TSO 61-519 GRS-16 PE v2 Parallel Edge Guide Rail Square for Festool, Milwaukee and more

Introducing the newest version of the best-selling guide rail square on the market: the GRS-16 PE v2. Designed to make it much faster to achieve dead square cuts with our track saw, our newest square improves upon the original GRS-16 by adding a second "parallel edge" to permit squaring against the front and back of our workpiece.

Simple, Automatic Accuracy: Before the GRS-16, methods for squaring a track saw relied on the loose-tolerance T-slot found in every guide rail. To overcome this inherent inaccuracy, woodworkers relied on a separate reference square, plus a combination of loose parts like T-bars, hex bolts, and knobs. These shop-made solutions would often quickly fall out of square, requiring constant vigilance and recalibration to maintain accuracy.

The patented GRS-16 PE solves this problem with a simple one-piece design that self-squares as it attaches to the guide rail. Once the powerful draw latch is engaged, the GRS-16 PE becomes a rigid extension of our guide rail, providing two precise 90° reference edges that won’t fall out of square over time. Despite its high clamping strength, a comfort coating on the latch handle makes it easy to generate the leverage necessary to engage, release or reposition the square along our length of track.

The GRS-16 PE is precision CNC machined from a single piece of 5/8" (15 mm) thick 6061-T6 aluminum and anodized for a non-marring, durable finish. The GRS-16 PE is made in Minneapolis, United States, and comes with a five-year warranty.
