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, 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.

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!

Perfect
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
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.

GRC-12 SELF-ALIGNING GUIDE RAIL CONNECTORS
The GRC-12 Self-aligning rail connectors function as advertised, I connected two tracks without using a straight. I checked after with an eight-foot level and voila.

Straight rails 100 percent of the time
I have 75” and 55” festool rails and the accuracy with my TSO parallel guides+GRE guide square is unmatched. TSO products are the best. Nothing comes close!
