The FITFINDER 1/2 Gauge allows you to find the 1/2 thickness of any material up to 3″ thick. Create perfectly fitting joints with zero guesswork, set fences and transfer cutting depths instantly—all with no math or measuring.
The FITFINDER was conceived while founder and inventor, Henry Wang, was developing the Dado Stop. While the Dado Stop solved the problem of cutting the width of a dado, setting the dado’s depth for half-laps still proved challenging. Henry realized that the solution was already there—from a Greek mathematician that lived over 2 millenia ago—Pythagoras. He applied this simple principle of geometry to a common woodworking process, and the FITFINDER was born.
