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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eByrne 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.\u003c\/p\u003e\n\u003cp\u003eIt is compatible with most rails on the market, including Festool, Makita, Bosch, Mafell, Metabo, and DeWALT tracks. If you run more than one brand of rail, one stop covers them.\u003c\/p\u003e\n\u003cp\u003eWho should buy this: cabinetmakers, finish carpenters, and anyone breaking down plywood and MDF with a track saw.
