The StealthMounts Trax90 XL Track Saw Square ensures that you are able to instantly and securely hold your guide rails at a perfect 90 angle for easy as well as accurate sheet cutting. The Trax90 XL provides instant material alignment for your plunge saw track. The extended lipped square edge provides instant material alignment and combined with integrated vacuum hose guidance, this saves time and increases cutting accuracy. The vacuum hose guides stop your hose or power cable catching on the edge of the track or getting in the way - smoother cutting with no more snagging. The Trax90 XL holds firmly using a unique integrated sprung slide design so there is no need to make any adjustments or deal with tightening clamps. Trax90 XL can be slid off from the track from time to time if required, though it is designed to be left fitted to the track to avoid wear. Made in Great Britain, the Square is made with tough injection moulded ABS Plastic to ensure durability and long life. It can even mounted on your workshop walls with the Stealthmounts Cleat N Feet set.
