GRS-16 PE K: Guide Rail Square for Kreg®
The original, patented precision guide rail square now compatible with Kreg's Adaptive Cutting System
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.

Warranty & Returns
Put it on my Kreg track and got perfectly square cuts. One of the better investments I have made
This square was so helpful for an on site cabinet build. It is a true 90 when attached to my track. Love this thing!
An awesome product that is easy to use.
Haven't gotten to actually use it, that's coming but looks great and is super secure on my track. I'll be adding the parrell guides as well
I really like this guide rail square. It attaches tightly to my track and is square. It makes it easier and quicker to make cuts on plywood and square up the ends of plywood without having to mark the plywood with a square and draw lines. The guide rail square also provides a hand hold to make sure the track doesn't shift while making a cut. The TSO product is also of very good quality.
