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've had the Makita SP6000 track saw for 3 years now and it gets used a lot both in the shop and on site. Where it really shines for me is working with sheet goods, which I do a lot of as a cabinet maker. In addition to reviewing the Makita, I will share some of the ways that I use the saw in my work and which accessories that I find helpful.
