The original guide rail square: the fastest way to square, accurate cuts with your FESTOOL, MAKITA and TRITON guide rails. Rather than relying on loose-fitting and imprecise T-slot hardware, the patent-pending GRS-16 is completely self-contained and self-aligning thanks to an innovative, high strength integral draw latch mechanism. Simply slide the GRS-16 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 is precision CNC machined from a single piece 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.
The GRS-16 is proudly made in the United States, and comes with a lifetime warranty from TSO Products.
