Keep Your GRS-16 Handy

Many woodworkers love using the GRS-16 Guide Rail Square with their Parallel Guide System — it’s a fast way to move from parallel rips to perfectly square crosscuts. With Parallel Guide System Gen 2, we redesigned the Parallel Guides to be universal, making the system easier to set up and faster to use. To preserve GRS compatibility, we created the Guide Rail Square Connector: a purpose-built interface that securely joins your GRS-16 to your Parallel Guide System Gen 2 Tracks.

Better than Before

The original TPG-to-GRS connection worked, but it wasn’t perfect. It obscured your view of the GRS-16 reference edge, making it harder to confirm you were fully registered against the workpiece. The new Guide Rail Square Connector fixes this by offsetting the GRS-16 from the Parallel Guide Track, giving you a clear line of sight and ensuring positive, even contact with the material’s reference edge. The result: true 90° cuts you can see and trust.
