The ThinRip Guide provides a perfectly safe stop on the offcut side of the blade, ensuring that you get the same-sized strips repeatedly as you move your fence closer to the blade. Using the ThinRip Guide is straightforward: slide it into the T-track miter slot of your table saw and lock it a few inches in front of the saw blade. Set the desired dimension on the laser-engraved scale, lock your fence, and make the cut. Whether you’re working with portable jobsite saws or large cabinet saws, the ThinRip Guide adapts. It fits miter slots that are 3/8″ x 3/4″ with a T-slot, allowing you to cut strips as thin as 1/32″ (or even thinner if the wood permits) up to 1-1/4″. Calibrating the scale to your saw is simple—align the bearings with the saw blade teeth and adjust the scale indicator. The anodized aluminum body features laser-engraved scales in both millimeters and inches. Plus, the included wall-mountable Rack-It™ keeps your ThinRip Guide handy and ready for use. Crafted from top-quality aluminum, this tool provides solid support and durability for generations of woodworkers.
