TSO Products 61-517 GRS-16 Guide Rail Square

Introducing the newest version of the best-selling guide rail square on the market: the GRS-16. Incorporating a number of user-driven enhancements, the TSO GRS-16 guide rail square is still the fastest, easiest and most accurate way to square cuts with your Festool, Makita, Milwaukee, Powertec and Triton track saw guide rails.

Simple, Automatic Accuracy

Introducing the fastest way to dead square cuts with your track saw: the GRS-16 Guide Rail Square. With its custom-made and powerful draw latch, the GRS-16 instantly self-squares while it clamps down to your track. And with a one-piece design made from a solid chunk of CNC-milled aluminum, you won't have to worry about losing that screw, clamp or other necessary accessory. Simply slide the GRS-16 onto your guide rail, clamp it down, and get to work.

Accurate cuts with your track saw may require using a screw or quick clamp to secure the guide rail to your workpiece. For this reason, the GRS-16 features notches to accommodate popular clamps from Festool, Axminster, or the like.

Built to be a Lifetime Tool

The GRS-16 is precision CNC machined from a single piece of 5/8" (15 mm) thick 6061-T6 aluminum and then anodized for a non-marring, high durability finish. The high-strength draw latch is custom-made from stainless steel to resist rust and pitting 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 your length of track. The GRS-16 guide rail square is made in the United States, and comes with our five-year warranty.

A System Approach

The GRS-16 is much more than a guide rail square; in fact, it's the foundation of a broader system of TSO Products designed for interoperability. Case in point: the GRS-16 includes attachment points to connect to the TSO Parallel Guide System. Once connected, you can repeatedly square and parallel rip multiple workpieces in a single operation.
