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, Triton, and Kreg ACS 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 guide rail connectors solve 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!

This is the way Festool should have designed their connectors. Excellent engineering and quality. The self-aligning feature and set screws make using these a snap. Thanks for designing a great product.
I originally bought some Makita guide rail connectors. I was unimpressed with the flimsy, thin piece you are supposed to use in one slot... It doesn't even have screws to hold it in place! The machining on the TSO guide rail connectors is so nice and accurate, it locks my two pieces of track together solid, rock solid! The machined 'lip' just makes these so much better designed and work so much better than the first ones I bought! Worth every cent!
I was thrilled to see the quality and craftsmanship in these rails compared to other brands and even Kregs own version. Everything you need is included in kit and the track stays locked solid and secure through normal everyday use and abuse. Thanks!
I purchased 2 sets of these connectors. One is mine for use with a Makita track and saw. The other was for my neighbor who has a Festool track and saw. We are both very pleased with the TSO connectors. They hold tightly and bring the tracks together with no effort on the user's part. I highly recommend these connectors for anyone whose track will accept them.
Can’t recommend these connectors enough, these are hands-down the best connectors in the market and are worth their weight in gold in comparison to cheaper models.
Perfect as always from TSO!!
They work great.
Good for connecting rails of say 1400 and under but if connecting say a 1400 to a 3000 the aluminium just doesn’t have the strength and easily bends. The festool equivalent are far stronger. Pls make this out of real steel.
These are so much better than the makita connectors. Fit and finish is flawless, and the one piece construction provides a more secure grip within the slot.
