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!

I’ve been using the GRC-12 Self Aligning Guide Rail Connectors now for about 4 Months. I had a Betterley’s that worked alright, but took some tome to make sure you had everything just right. With the GRC-12, there is no fidgeting to get everything right. It’s just right straight away when you tighten the set screws. And with the GRC-12 screws, there is no dimpling the guide rail.
This product is very well made and uses the best of materials available. I’m very pleased with everything I’ve purchased from TSO and they have very quick turn around on shipping out their products.
These are so much better than the bars that festool makes! It's almost embarrassing to Festool how much better these are. The rails are just straight now, with no messing around to get them there. They just work.
very nice product, a usefull replacement for the festool rails, the alignement is perfect.
I'm really happy with the guide rail connectors. They are well finished and slid right into the rails and lock securely. Alignment was right on. Customer Service was also excellent; I had a small issue with the included driver and they were really responsive and got a replacement sent right out.
Having frustrating experiences with Festool's own expensive guide rail connectors (which are for some reason not sold in pairs?) and stripping the flat-head screws in those connectors, I was blown away by the fit and finish, and functionality, of these connectors. The self-align feature works well, and the custom mushroom bolts have a huge amount of additional purchase against the guide rail. Hex head is always preferred to flat-head as well. Another TSO win!
I love them. they come with its own screwdriver and you do not nat have to try to find a small flat head. They slide effortlessly.
Works super on my Makita guide rails. I checked several cuts with Makita connectors and then the TSO. Slight deviation with single Makita connector, straight as an arrow with the double TSO connectors.
An awesome product, easy to use and store. Perfect alignment of my Festool guide rails
Simply brilliant and so easy to use.
