Description

Original, Patented Guide Rail Square for FESTOOL®, MAKITA®, Milwaukee®, POWERTEC® & TRITON®

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.

Featuring New Enhancements

Thanks to feedback from the TSO user community, the GRS-16 guide rail square now includes:

  • Our lightest design ever despite being CNC machined from 25% thicker aluminum, with a mating vertical edge providing maximum guide rail support
  • Latch hook resilient coating grasps and protects the edge of your guide rail
  • Easier to install onto your guide rail with a reshaped T-feature lead-in
  • Accessory mounting holes tapped for M6 threads—enables connection to the TSO Parallel Guide System and Angle Accessory
  • Available Dual FoamPac Systainer Insert fits both the GRS-16 and GRS-16 PE in a single Systainer
  • New, fully recyclable all-corrugated white packaging

See How It Works

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.

Compatible with guide rail clamps

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.

So Which Tool is Right for You?

If you want the absolute smallest and lightest form factor and anticipate using the square for conventional cuts referencing the front edge of your workpiece, choose the GRS-16 (the product you see on this page). If you need the ability to reference off the front and back edge of your workpiece, select the GRS-16 PE.

Connect your GRS-16 to the TSO Parallel Guide System

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.

    Best tracksaw accessory on the maket

    Posted by Howard Dove on 5th Apr 2017

    The GRS-16 works - no fiddling around with nuts, bolts, moving parts. Even a relative newby, like myself, can use it like a professional would. I'm making a bench for my MFT3 to sit on out of laminated ply and was able to cut all the stock within minutes of opening the parcel. I don't have a table saw, but even if I had, this tool would be my "go to" tool to break down sheet goods. Before the GRs-16 I had to juggle with track and square and clamps to make one cut. Now I do t even bother with the clamp, butt it up to your piece and cut and your done.

    Just flat out amazing!

    Posted by Robert Deever on 18th Mar 2017

    I've been doing woodwork for almost 50 years and I'm always looking for products that make things easier. This is one of those products that is...high quality with ease of use and 100% accurate right out of the box. I've only written two reviews over the years and this is one of them. It's not that other products were not good. I have many really nice tools. However, when something comes along that is amazing...then I take the time to encourage others with my review. If you own a track saw, I highly encourage you to order one of these. You will not be disappointed. Thank you!

    If You Need Square Cuts

    Posted by Ben Rich on 2nd Mar 2017

    I'm currently in the process of building cupboards and cabinets in my garage. I'm not a professional so I need all the help I can get. This GRS-16 is worth the cost; I can now measure, place my guide rail with the GRS-16 to my mark, and get a square cut each time. It just works, and I have confidence in it... which I did not have in any of my previous methods.
