    TSO Guide Rail Square Anti Tip Support Tab

    Feature Overview

    The original TSO Guide Rail Square (GRS) Support Tab screws directly into the existing holes to keep your guide rail square secure and stable on your work piece. The guide rail squares are a great addition for squaring up your track saw to the work piece. One of the issues is that the guide rail squares have some weight to it which creates twisting as it weighs down the track. The support tab solves this issue by keeping everything flush.

    We've created two different versions for you to choose from. The short version uses one M6 star knob to secure the Support Tab into place. The longer version uses two M6 star knobs and has a longer surface area. Both options are a great addition to your arsenal. They are installed and removed in seconds.

    • Provides a support tab for TSO Guide Rail Squares (GRS-16 or GRS-16 PE)
    • Keeps your guide rail square and guide rail stable with your workpiece
    • Made out of high quality Carbon Fiber HTPLA
    • Attaches and removes easily using the factory M6 tapped holes


    The guide rail square will twist or sag towards the end due to the weight. This can make it inconvenient when squaring up to your workpiece.  The support tab will keep your guide rail square and guide rail flush to your workpiece.

    Uses Factory Threads

    No alterations and no tools needed. These will install directly into factory M6 tapped threads. Installation takes only a few seconds.

    Carbon Fiber HTPLA

    The plastic is made from a combination of real milled carbon fiber and high-performance HTPLA that is Made in the USA. Carbon Fiber HTPLA is demonstrably more rigid, providing excellent structural strength and layer adhesion compared to normal PLA. The finish comes as a beautiful matte black with a slight sheen due to the carbon fiber. This is truly the best plastic on the market through our testing (and the most expensive). Any other type of PLA will be inferior in strength and finish.

    Made in USA

    These are designed, made and quality control inspected in the USA. The plastic and hardware are sourced from USA based companies, supporting other American manufacturers.
