GRC-12: A Better Way to Connect Guide Rails
Watch this video to see how the GRC-12 auto-aligns and secures two guide rails at the same time, while eliminating the need for expensive straight-edges.
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!

Just got these to connect 2 55” Festool rails together . They work great and very happy with them. No adjustments needed once connected.
So happy I didn’t wait long to replace the connector the manufacturer provided - these are a world apart in both functionality and quality. Excellent tool and no-brainer upgrade - love the provided tool and fast shipping!!
These are the best guide rail connectors on the market!!
need your parallel guide system
These guide rails are perfect. I have 2 makita 51” tracks and tried the makita guide rails - couldn’t assure it was straight and true. Decided to try the TSO guide rail connectors as I was impressed with the machining. Well they work perfect -100x better than the Makita fit the rail assure alignment TSO all the way. Thanks for making a great product to improve the performance of our track saws
So easy awsome
I have two sets now to connect over 12' of rail. Work great! So fast and easy to connect and disconnect too.
I have to ask myself why Festool didn’t design theirs this way from the start. I also think of the supplied these is a few different lengths and hole patterns they would be a good jig making foundation for the rails.
