Johnson's digital t-bevel takes the guesswork out of angle duplication and eliminates problems with analog readings and manual measurement transfer. Measure, hold and transfer interior and exterior angles quickly and accurately. Its durable stainless steel blade is rust resistant, and the impact resistant ABS handle is built to last. Large easy reading LCD can be inverted 180° at the press of a button for precision measurements from 0 to 360°. Practical function modes make it handy for reverse miter angles and holding current values.
