The Brown Line Metalworks Digital Angle Gauge (DAG) quickly and easily attaches to the shaft of any standard ratchet, breaker bar or wrench. It give the user a quick, easy, and convenient way of measuring angular rotation for torque-to-yield or torque-turn applications. It can save a technician significant time when using these fasteners as compared to a manual angle gauge or marking method. It can be used on any size drive / handle, so unlike a digital wrench with an angle function built in, the user is not limited by the upper range of the torque wrench. A backlit LCD screen, colored LEDs and an audible buzzer make using the DAG simple and intuitive, and a “ratcheting” feature allows the unit to be used on a ratchet without losing track of forward progress. The gauge works with any size drive: 1/4", 3/8", 1/2", 3/4" or 1".
