There are a variety of accessories available that add to the accuracy and capability of a track saw, and the GRS-16 guide rail square is one of those accessories. In this review I will go through the design and features of the GRS-16's, explain how they work and I also share my real world experience with them after putting them to work in my shop.
I have just finished designing and building a new MPT style worktop for use with Bosch or Sortimo L-Boxxes! This new worktop has the same system of 20mm holes as the MPT and therefore can be used for some of the same tasks with some of the same accessories. I've also created a full set of plans similar to the MPT plans. For jobs where you don't have space to set up the full MPT or jobs that are too small to require it, this is the perfect solution.
