Key Features
Overview
The Byrne Square Track Stop (model BN-FS 90, Byrne item 180963) is a guide rail square for track saws. This is a track saw accessory designed for making fast, repeatable 90-degree crosscuts on sheet goods and panels without laying out a square line first.
The stop attaches to the underside of the guide rail and hooks against the edge of the workpiece. Push it tight to the panel edge, drop the rail, and the rail is square to that edge. That is the whole setup. It turns a track saw into a crosscut station for cabinet parts, shelves, and panel work where every piece has to match.
Byrne CNC-machines the body from aluminum alloy, which is why it holds a true 90 degrees. Stamped steel squares and plastic rail stops flex under pressure. A machined aluminum body does not. At 1.1 kg (about 2.4 lb), it has enough mass to sit flat and stable against the rail.
It is compatible with Festool, Milwaukee, Makita, Triton, and Kreg guide rails. If you run more than one of those rail brands, one stop covers them.
Who should buy this: cabinetmakers, finish carpenters, and anyone breaking down plywood and MDF with a track saw. If you are still squaring rails off a pencil line, this saves time on every single cut.
Square to the Edge in Seconds
Hook the stop on the panel edge, drop the rail, and cut. No square, no pencil line, no second-guessing.
- Registers the rail at 90 degrees
- Repeatable for batch cuts
Machined, Not Stamped
The aluminum alloy body is CNC-machined, so the reference faces are flat and true.
- Aluminum alloy construction
- Stays stable against the rail

Pro Tip
Check the stop against a known-square cut the first time you mount it on your rail, then cut a test panel and flip it to verify. Once it checks out, you can trust it for the rest of the job.
Tool Nut's Take
The Fastest Way to Square a Track
The Byrne Square Track Stop makes square crosscuts with a track saw as quick as dropping the rail.
- Who it's for: Anyone breaking down sheet goods with a track saw who wants repeatable square cuts without layout.
- Why it stands out: CNC-machined aluminum and compatibility across Festool, Milwaukee, Makita, Triton, and Kreg rails.
- Worth knowing: It references the panel edge, so the panel edge needs to be straight for the cut to be square.
Common Questions
- Which guide rails does it fit? Festool, Milwaukee, Makita, Triton, and Kreg guide rails.
