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.

    Save time, save money, improve quality

    Posted by Jon Lake on 17th Feb 2017

    In my small workshop cutting a decent sized sheet of plywood square can be tricky sometimes, and I can't justify spending GBP500 on a Festool MFT. Well, the solution has turned out to be the GRS16. I wasn't the cheapest piece of aluminium I've ever bought but it's quality and performance more than justify the expense. I can cut square every time with ease and speed. Faster, more accurate and simpler setup saves time and money. I wish I'd found this earlier, and I''ll likely order the PE version soon. You won''t regret buying one of these guides.

    Works really, really well.

    Posted by Ross Davis on 16th Feb 2017

    This is a time saver for me. Just make sure you have a clean edger to reference from. After that, there is little / no need to check for square when making the cut. Well worth the money in my mind.

    Great Product, Fantastic Service

    Posted by Dennis T on 31st Jan 2017

    I recently purchased the GRS-16 - it's extremely well made and is a fantastic addition to my workshop. I use it with a Makita Track Saw and it cuts work time in half (pun intended). I had a problem with some sort of glitch in the website when I was trying to order the product and I had to contact TSO. It was a very enlightening experience - the people at TSO are not only knowledgeable but extremely helpful. It's so good to know that you are dealing with a company that's actually nice. I know it doesn't make the tools any better or worse, but it makes you feel good about working with a company that cares about the products and the services they deliver to their customers. I am a big fan and a newly loyal customer.

    After a little problem with the shipping number, I contacted TSO. Han's got back with me right away and took care of the problem. Their customer service is second to none. The Guide Rail Square works great and is a time saver.

    handy to have

    Posted by George Luck on 28th Nov 2016

    Until I received this product is had square my rail on my sheet materials either with a roofers square or by accurately measuring but with the guide rails quarts it's instant. If you cut a lot of sheet material you really need to get this. My only complaint is they don't do a rail square for the Mafell yet !!!! >>>NOTE from TSO Products: >>>Mafell is on our radar, stay tuned!
