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.
Wood dust is definitely a health concern and we are becoming more aware of that in recent years. In addition to being bad for your health, wood dust is also time consuming to clean up. The more dust you can capture at the source, the better off you are. Less time cleaning up means more time woodworking and doing what you love. As a professional, in my case and in many others it also means more production time which means more profit.
