<p>A Multifunction tool that measures in 3D! Accurately calibrate tools, check your work, and space pieces for fast placement. The Step Gauge 3D ruler is a patented multifunction tool that measures in three dimensions. The revolutionary two-piece tool allows you to calibrate tools quickly and accurately, check your work, and space pieces for fast placement. Use the 3-D ruler?s large and small parts separately or stacked together. Its patented design allows you to measure height and width in one single step. Your fingers can feel 30 times more accurately than your eyes can see. The 3D ruler helps you be a more precise craftsperson. No Squint Precision. This is what sets the 3D ruler apart from most other measuring devices - it enables you to measure, calibrate, and check your work using your sense of touch rather than your eyesight alone. If you can feel it with your fingers you will get more accurate results than if you just compared lines on a tape measure or ruler.</p> <b>Features:</b> <ul> <li>The 3D ruler?s function as a gap gauge is another great feature that saves time and prevents errors while working in the shop.</li> <li>Dimension - 14 x 3 x 6 in.</li> <li>Item Weight - 5 oz.</li> </ul>- SKU: NRAS001
