GRC-12: A Better Way to Connect Guide Rails
Another TSO innovation, the GRC-12 is a first-of-its-kind, self-aligning guide rail connector for use with Festool, Makita and Triton brand guide rails. Before the GRC-12, aligning connected guide rails required a variety of methods and additional tools to achieve straight connections, with misalignment often difficult to detect without a long straight edge or similar tool. This issue becomes obvious too late - when gaps show up during assembly or glue-up.
The GRC-12 solves this problem with a completely self-contained and self-aligning design - thanks to an innovative integral keystone feature. Simply slide the GRC-12 into your guide rail T-slots and firmly tighten the set screws - that's it.
Because small hex wrenches can be annoying to deal with, we’ve solved that too: the included ball hex driver drops easily into the hex socket and is large enough not to get lost or easily overlooked.
Key Features of the GRC-12
- Connects AND aligns in one operation, with no need for secondary tools such as a level.
- Easy, fast, accurate!
- Only perfectly aligned rails can produce perfectly straight cuts.
- Unique Patent Pending design helps keep rails aligned.
- GRC-12 keeps rails aligned with it's Keystone-shaped Connector feature.
- Connected and DONE!

They clamp tracks perfectly
I used these for connecting two Festool guide rails. They worked very well with minimal adjustment needed.
Full disclosure, I work for a Festool dealer and have significant experience with their products. Functionally TSO's guide rail connectors exceed Festool's in every way. The use of non-dimpling screw feet is a winner. The use of a ball end allen wrench is also superior. The materials selection of stainless steel and the machining is superb. But the real advantage is the self-aligning feature of these connectors. No longer will one need to do tricks with a straight edge or mounting the track saw for alignment. Great job TSO.
Great addition that allows my Makita rails to be perfectly aligned. Much better than the stock Makita rails.
Aligns the rails straight as intended. The quality was lower than I expected for the price and from TSO (came with a gouge and feels like one drop will throw it out of straight).
I had already purchased TSO’s guide rail square, and was very impressed with the performance and accuracy of the square. I needed a set of guide rail connectors to mate my Festool rails, and was all set to buy the FS product, when I noticed TSO’s connectors. What drew my attention was the self-aligning feature, presumably to keep you from having to fuss with a straightedge every time you want to connect rails. Well, after purchasing TSO’s connectors and putting them to use several times now, I am very happy with my purchase. The connectors just work, the first time, every time. The rails are dead-on straight without having to fuss with a straightedge and readjusting like you have to do with competing products.
Easy to use, easy to install, easy to uninstall. self-aligning, and precise connection every time.
I've used the Betterly track alignment jig with the Festool rail connectors. The TSO rail connectors are not only easier to use but they are also faster, cheaper, and won't damage the track. I would buy these again in a heartbeat.
If you’ve ever used guide rail connectors from the likes of Fe$tool or Makita, then TSO’s will be a revaluation. Slide them in, tighten up, the end. No messing about with straight edges, tighten, loosen, turn rail over, find things have shifted, repeat, repeat, repeat. These just work. Buy them. So good, I have two sets.
