Festool
These are an absolute game changer. No more crooked rails. Why did it take Festool so long to sort this? Recommended.

Festool joining bars.
You can’t go wrong with festool. Although these look relatively the same as the original joining bar you can tell the difference when using the new version. I can’t fault them.

Much improved but pricy!
I had delayed buying these improved Festool track connectors as the price was eye-watering. So I was glad to eventually buy two sets with a substantial discount. Yes, they are better than the old Festool parts but still not as good as the Mafell locking system. Two tips: ensure the tapered screw is fully backed out before trying to fit the expanding connector in the track. Add a drop of Loctite 222 (soft) to lightly retain the grub screws so they don’t vibrate loose or fall out when not clamped.

they only self algin half the time , and if you move the fence around a lot they are difficult to unscrew. still better than the old bars but manage your expectations
