TSO Products Guide Rail Squares

Guide Rail Squares from TSO Products
There's no quicker way to square your FESTOOL®, MAKITA® & TRITON® track saws

Until now, 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. Not any 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 GRS-16 or GRS-16 PE onto your guide rail, lock the draw latch, and you're done. Five seconds to square.

Engineered for maximum accuracy and ease of use, the GRS-16 and GRS-16 PE are precision CNC machined from single pieces of 6061-T6 aluminum and then anodized for a non-marring, high durability finish. Once secured to your guide rail, squareness can be quickly verified by observing the zero-clearance attachment between the square and guide rail. Despite its high clamping strength, your guide rail is completely supported by the straight-edge of the GRS-16, eliminating any potential for track deformation over time. An ergonomic handle makes it easy to lift and reposition the square along your length of track, and machined chamfers improve comfort and handling. Both the GRS-16 and GRS-16 PE are made in the United States, and come with our unconditional lifetime warranty.

So Which Tool is Right for You?

Reasons to choose the original GRS-16:

  • Smallest and lightest form factor for easier handling and convenience, in the shop or on the job site
  • Stores nicely in a FESTOOL SYSTAINER T-LOC SYS 1 TL (see our optional FoamPac Storage Insert)
  • Ideal for conventional cuts made referencing off the front edge of your workpiece

Reasons to choose the GRS-16 PE:

  • Permits referencing off the front and back edge of your workpiece
  • Retains all of the functionality of the original GRS-16 guide rail square

Reasons for choosing both the GRS-16 and GRS-16 PE (the version you see on this page):

  • 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
