Product Description
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, Milwaukee, Kreg ACS, POWERTEC, 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 TSO 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!

GRC-12 SELF-ALIGNING GUIDE RAIL CONNECTORS
After doing my research the self aligning guide rail by TSO seemed like the best option, fits great in the rail, sturdy construction, and over all great design.

Aligning rail connectors
The the connectors are really nicely made and of good quality. The fit is perfect making the two pieces of guide rails connect tightly together. A little pricey but works perfect. Compare to the one that the brand saw sales these are the best. Specially if you are connecting rails constantly together these are much faster and easy to connect. 4 stars just because of the price. A little to high.

Precision Alignment
No more worrying about straight long cuts when joining my Mikita track saw guide rails. Rails are automatically aligned with precision machined bevels. Included hex screw driver is a plus.

Worth the Upgrade
I upgraded from the Makita's product to this. Absolute game changer. These are so much better its no real comparison. I would recommend them without reservation.

No magic here
There is no magic to these. I have to use a straight edge to ensure my guide rails are parallel and now I’m $60 poorer. Seemed promising but these don’t work any better than less expensive models.

Get-12 rail connectors
I had really high hopes, but honestly didn’t think these rail connectors would actually alleviate my frustration with the Makita ones. But according to my best straight edge (a 6’ r-beam Stabila), they work perfectly! I’m seriously in love with them and actually look forward to connecting my rails!

GRC-12
I needed to purchase guide rail connectors for a Kreg track. Kreg was not only out of stock but availability was until March 2023. I was somewhat hesitant to buy the TSO alternative because Kreg said only theirs would fit. When these arrived I immediately had to try them out. Not only did they fit, but the fit better and aligned easier! Thank you TSO!
