The Original (& Patented) Guide Rail Square

Thanks to feedback from the TSO user community, the GRS-16 PE parallel edge guide rail square embodies a number of requested features and refinements:

• Lighter than its predecessor despite being CNC machined from 25% thicker aluminum, with a mating vertical edge that now perfectly matches the height of your guide rail extrusion for maximum support and engagement

• Now fits in a Systainer—see our new Dual FoamPac Systainer Insert and limited edition TSO Blue Systainer3 M 112

• The latch hook now features a resilient coating to grasp and protect the edge of your guide rail

• Reshaped T feature lead-in makes it even easier to install onto your guide rail

• Accessory mounting holes tapped for M6 threads—enable connection to the TSO Parallel Guide System and Angle Accessory

• Adjustments to key tolerances to better accommodate production variances observed in guide rail manufacturing

• Fasteners used on all TSO brand tools are now metric for worldwide availability

• New, fully recyclable all-corrugated white packaging
