GRS-16 PE D: Guide Rail Square for DeWalt®

The original, patented precision guide rail square now compatible with DeWalt 60V MAX cordless and corded track saws

GRS-16 PE D Guide Rail Saw for DeWalt Track Saws Introduction Video
Watch this video for an introduction to our GRS-16 PE D guide rail square for DeWalt 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!

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

Much more than just a guide rail square, the GRS-16 PE D is the foundation of a broader system of TSO Products designed for interoperability. In fact, the TSO Parallel Guide System connects to the GRS-16 PE D via its included M6 accessory mounting holes. Once attached, you can repeatedly square and parallel rip with your DeWalt track saw in a single operation.

    Good addition to a DeWalt track saw

    Posted by John H on 22nd Jun 2023

    It's as good as they can make it, given the limitations of the DeWalt track. But, you really need two, one for each side of sheet goods, especially when cutting the long side, to be accurate when using the parallel guides. The track doesn't move very easily, and checking that it's completely aligned with the edge is hard to see, as the track guide covers the intersection of the square and the board. I may buy a second.
