GRS-16 PE K Guide Rail Square for Kreg

The Original Guide Rail Square, Now Compatible with Kreg's Adaptive Cutting System (ACS)

The proven design of the GRS-16 Family has now been adapted to fit Kreg's track saw cutting system! Like the original GRS-16 and GRS-16 PE squares, the GRS-16 PE K makes it faster to achieve dead square cuts with your Kreg Adaptive Cutting System Plunge Saw. With two reference parallel edges, the GRS-16 PE K permits squaring against the front or back of your workpiece.

Part of TSO's system approach to woodworking, the GRS-16 PE K is compatible with the TPG Parallel Guide System.

The GRS-16 PE K 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 TSO Parallel Guide System connects to the GRS-16 PE K via its included M6 accessory mounting holes. Once attached, you can repeatedly square and parallel rip with your Kreg track saw square in a single operation.

GRS-16 PE K Highlights

Thanks to feedback from the TSO user community, the GRS-16 PE K incorporates all of our latest design innovations:

• Ultra-light and balanced design machined from 6061-T6 aluminum, with a mating vertical edge that perfectly matches the height of your Kreg guide rail extrusion for maximum support and engagement
• Two squares can now fit in a single Systainer—see our Dual FoamPac Systainer Insert and limited edition TSO Blue Systainer3 M 112
• Custom high-strength stainless steel latch with resilient coating to grasp and protect the edge of your guide rail
• Filleted T-feature lead-in makes it even easier to install onto your guide rail—"five seconds to square!"
• Accessory mounting holes tapped for M6 threads—enables connection to the TSO Parallel Guide System and Angle Accessory
• Sustainable, fully recyclable all-corrugated white packaging

See How It Works

The design of the GRS-16 PE K is based on our popular GRS-16 PE square, and shares the same features and benefits. See the GRS-16 PE K put to use in the video below.

Simple, Automatic Accuracy

Before the GRS-16 family, accessories for squaring up your track saw guide rail relied on the loose-tolerance T-slot found on just about every guide rail. To overcome this inherent inaccuracy, you had to rely on a separate reference square, plus a combination of loose parts like T-bars, hex bolts, knobs or wingnuts. No longer! The patented GRS-16 PE K is completely self-contained and self-aligning, thanks to an innovative, high strength integral draw latch mechanism. Simply slide the GRS-16 PE K onto your guide rail, lock the draw latch, and you're done. Five seconds to square.

Accurate cuts with your track saw often require using a screw clamp or quick clamp, sliding into a guide rail T-track. For this reason, we've designed notches in both reference edges of the GRS-16 PE K to accommodate popular screw clamps and rapid clamps.

Built for a Lifetime of Service (or Longer)

The GRS-16 PE K 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 built 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 PE K is made in the United States, and comes with our five-year warranty.
