GRS-16 & GRS-16 PE Combo Set
Precision guide rail square for FESTOOL®, MAKITA® & TRITON® track saw guide rails
Enjoy special savings when you purchase both the GRS-16 and GRS-16 PE as a combination set. The GRS-16 and GRS-16 PE are designed to make it much faster to achieve dead square cuts with your FESTOOL, MAKITA or TRITON track saw. Keep one in the truck and one in the shop, or use both guide rails at the same time to square either ends of longer guide rails.
The Original Guide Rail Squares, Refined
Thanks to feedback from the TSO user community, these latest squares embody a number of requested features and refinements:
- Lighter than its predecessor despite being CNC machined from 25% thicker aluminum, with a mating vertical edge that now perfectly matches the height of your guide rail extrusion for maximum support and engagement
- Both squares now fit in a single Systainer—see our new Dual FoamPac Systainer Insert
- Latch hook now features a resilient coating to grasp and protect the edge of your guide rail
- Reshaped T feature lead-in makes it even easier to install onto your guide rail
- Additional accessory mounting provisions included—see our new Angle Accessory and stay tuned for some exciting new products building off the GRS-16 platform
- Adjustments to key tolerances to better accommodate production variances observed in guide rail manufacturing
- Fasteners used on all TSO brand tools are now metric for worldwide availability
- New, fully recyclable all-corrugated white packaging
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 patent-pending GRS-16 and GRS-16 PE are completely self-contained and self-aligning, thanks to an innovative, high strength integral draw latch mechanism. Simply slide the square 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 or quick clamp. For this reason, we've designed notches in both reference edges of the GRS-16 PE to accommodate popular clamps like the Festool Screw Clamp or Quick Clamp.
Built for a Lifetime of Service (or Longer)
The GRS-16 and GRS-16 PE are precision CNC machined from a single piece of 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—and features a resilient, grippy, non-marring coating on the latch hook. 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. Both the GRS-16 and GRS-16 PE are made in the United States, and come with our lifetime warranty.
The Best of Both Worlds
When you need 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. When you need the ability to reference off the front and back edge of your workpiece, select the GRS-16 PE. Or, choose the Combination Set for the best of both worlds:
- Allows you to square both ends of longer rails for greatest accuracy
- Keep one in the truck and one in the shop
- Special savings when purchased together as a Combination Set
- Dimensions (Both): 15.2 x 6.0 x 1.4 inches (385 x 152 x 36 mm)
- Weight (GRS-16): 1.7 lbs (772 g)
- Weight (GRS-16 PE): 1.9 lbs (862 g)
- Material (Both): 6061-T6 aluminum, anodized, 5/8 in (15 mm) thick
- Compatible Guide Rails (Both): FESTOOL, MAKITA and TRITON (not compatible with FESTOOL HK 55 Carpentry Saws including the FSK 250, FSK 420 and FSK 670; not compatible with BOSCH or DEWALT tracks)
- Clamping Mechanism (Both): Over center draw latch (304 stainless steel) with compensating spring; secured with M4x0.7-10 stainless steel socket head screws

A very accurate tool, Exellant quality. Very happy with it and i highly recommend it
So far, they're working exactly as advertised. Rock solid 90 degrees to the rail. The only reason I withheld a start is that I haven't used them long enough (yet) to give them unreserved support.
So why am I reviewing it now instead of waiting? TSO emailed asking me too!
Rail square where great out of the box .I needed to cut down 12 door was done in about two hour, that because all the work remove from door jamb and reinstall . Great product fast and accurate.
Well what can I say just started to use today for the first time and I noticed that the plate needs to be a little thicker and longer or at least provide the extension for that price
Yes it does cut true 90 degree yet you need to make sure it’s held down properly
Perhaps I’m still getting use to it not sure
I did try to order the angle aluminum but it’s out of stock for now
I’ll do an update soon hopefully it’ll work to my benefit
Great product a bit overpriced
very well made and easy to set up
Amazing product. Durable and rugged. Did a progect last week and these two tools combined cut my table saw time by 80%. The safety factor of not being on the table saw alone is a huge plus. No alignments needed. Square cuts!! This takes a economic Triton track saw and turns it into a beast! Highly recommend this product. Cutting down plywood for cabinets used to be my nightmare in my tight garage. No more!! The grs products have made that a super easy and precise task.
An awesome add on for your Festool track saw. Makes a great tool even better. You can't go wrong with TSO guides. Dead on accurate! Thanks TSO Products!
Anyone with a track saw should own this product. Simple set up/removal and extremely accurate. Squaring up really anything is quick and effortless. Wish I had this years ago.
