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.
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, WEN, 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 M6 Mushroom Head 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!

    No magic here

    Posted by Richard on 6th Jan 2023

    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

    Posted by Toby Farnsworth on 1st Jan 2023

    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

    Posted by John Eggers on 10th Dec 2022

    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!

    Perfect

    Posted by Jack Davidson on 9th Dec 2022

    I heard the basic rail guides for Makita were not good, and expensive. These were recommended hands down by everyone and ended up being cheaper anyway. A must have if you’ve got multiple rails, don’t use anything else

    GRC-12 SELF-ALIGNING GUIDE RAIL CONNECTORS

    Posted by James Thomas on 28th Nov 2022

    I want to love these having 2 55’” rails to cut 8’ sheet goods but I’m very disappointed a waste of money. Using a 36”certified straight edge tighten up the top connector and flip it over to tighten the bottom connector it pulls the rails out of straight. I have tried like ten times same result ends up at the end of the rail 6mm unacceptable.
