StealthMounts Trax90 Track Saw Square for Festool Track Saws | 90° Right Angle Plunge Saw Guide Rail Angle Stop is a guide rail square designed to set a Festool-style track at a right angle to the workpiece edge. This is a track saw square designed for fast, repeatable 90 degree sheet cutting. Model Number: TSS-S-FT-1. If you break down plywood, MDF, melamine, or other panels and want quicker setup than measuring and clamping every time, this is the kind of accessory that saves real time.

The main job here is simple: slide the square into the guide rail, place the rail on your material, and push the square against the edge to set your cut. That gives you a consistent 90 degree reference for crosscuts and panel trimming. On the bench or on-site, that means less layout work before each cut and less chance of drifting out of square because the rail was bumped during setup.

One of the more useful details on this StealthMounts track saw accessory is the integrated vacuum hose and cord guide. Anyone who runs a plunge saw with dust extraction knows the hose can catch on the rail edge right when you are trying to start or finish a cut. By guiding the hose clear of the track, the Trax90 helps the saw move smoother and keeps the setup less fussy, especially when working alone with full-size sheet goods.

The construction is injection molded ABS plastic, which makes sense for this kind of accessory. It keeps weight down while still holding its shape for regular use. StealthMounts calls it one of the lightest rail squares on the market, and the listed weight of about 6 ounces backs up the idea that it will not make your rail feel awkward or front-heavy. If you like to leave accessories mounted on the track instead of pulling them off between cuts, lighter is usually better.

The mounting method is another practical part of the design. It uses a sprung slide design that holds in the Festool track without requiring clamps, knobs, or repeated adjustment. That matters because a square like this is only useful if it is fast enough to beat your usual workflow. No setup, no tightening, and no fiddling means you are more likely to actually use it for every cut instead of only on perfect bench setups.

StealthMounts also built in mounting points for use with Cleat 'n' Feet storage accessories, which is a nice shop detail if you already use that system. It lets the rail be stowed vertically while the square stays part of the setup. That is not the main reason to buy it, but for a small track saw guide accessory, smart storage compatibility is the kind of detail that keeps the shop from getting cluttered.

For fitment, this version is specifically sold for Festool track saw guide rails, and it is also compatible with Wen, Triton, and Power Tech track saw guides. It is recommended for shorter tracks up to 1200 mm or 48 inches, while the larger Trax90 XL is the version recommended for longer rails. If most of your work is cabinet parts, shelves, and general sheet breakdown on shorter rails, this standard Trax90 is the right size to look at.

Who should buy it? Woodworkers, cabinet installers, remodelers, finish carpenters, and serious DIY users who use a track saw for square panel cuts and want faster repeatability. If you rarely use a guide rail, you may not need it. But if your track saw is out every week and you are tired of checking square over and over, this accessory earns its spot pretty quickly.
