A Guide Rail Square Built for DeWalt's 60V MAX Cordless & Corded Track Saws
The proven design of the GRS-16 guide rail square has now been adapted to fit the DeWalt track saw system! Like the original GRS-16 and GRS-16 PE squares, the GRS-16 PE D makes it lightning fast to achieve dead square cuts with your DeWalt plunge saw. With two reference parallel edges, the GRS-16 PE D permits squaring against the front or back of your workpiece. The square attaches to your DeWalt track with a torpedo nut that automatically squares as it clamps down, resulting in a rock-solid attachment that won't fall out of square over time and will never need calibration. Simply slide the square onto your guide rail, secure the single flat head screw on the bottom of the plate using the included 3mm hex L-wrench (which stows magnetically on the face of the square so you never lose it), and you're ready to get to work.
DeWalt's guide rails are uniquely symmetrical and feature splinterguards on both sides of the track. We carefully designed the GRS-16 PE D so that it could be mounted on either side of the guide rail, without interfering with the splinterguards. "Other" tools on the market require you to cut off a portion of your spliterguard to mount the square, limiting where you can place and move the square along the guide rail; not so with the GRS-16 PE D!

Part of TSO's system approach to woodworking, the GRS-16 PE D is compatible with the TPG Parallel Guide System.

Accuracy takes some tweaking
I was excited to get this guide rail square. The first few cuts were with the 55 inch track and all was well. The 105inch track was harder to adjust. I spent about 2 hours measuring and re-measuring. I noticed that the aluminum block that goes into the bottom side of the track was a bit loose which allowed the square to be aligned at something close to 90 degrees but not dead on. Tnhat little aluminum block is not a positive stop which shows up on the 8 foot cuts using the 105-inch track. The instructions indicate to use the "5-cut" method for calibration. However, that works only until the square is removed from the track for storage.

GRS-16 for DeWalt
Although I haven’t been able to use it yet, I can tell it is a well engineered and manufactured product. The design is simple but well thought out.

A must have.
This definitely makes it into the game changer category for tools that we own. Very easy to set up / use & it provides a dead perfect square cut. Improves efficiency when that sort of cutting is required. The only heads up I will give to those looking to purchase this is that it will not work with the original beefier Dewalt track clamps. Not a big issue for us since we have both original & new style but if you only have the original you will need to buy the thinner / narrower clamps. Great add on accessory!
