Q: What guide rails does this fit?
It's built for Festool track-saw guide rails, and it also works with rails made by Triton and Makita.
86N5415 - GRC-12 Self-Aligning Guide Rail Connectors, pr

Used to link Festool guide rails for long track-saw cuts, these connectors automatically align the rails while being tightened in place, eliminating the usual adjustment process.
Machined from aluminum for strength and rigidity, each 12" connector slides neatly into the T-slots of both rails. As you tighten the four set screws with the included ball-head hex driver, the connector’s keystone shape is drawn firmly against the lip of the T-slot, pulling the rails into precise alignment and preventing them from shifting. Once installed, the connector doesn’t project above the T-slot, so it won’t obstruct your saw during the cut.
Quick to secure and release, this is a straightforward, reliable system. Compatible with Festool track-saw guides as well as those made by Triton and Makita. Made in USA. Sold in pairs.
Not available for shipment to Québec.

No, once it's installed the connector sits within the T-slot and doesn't project above it, so it won't obstruct the saw.
They're available in pairs, which is enough to join two rail sections into one continuous length.
