Description
Rieker's rugged manual boom angle indicators- the 4120 Series - are not effected by outdoor elements. These instruments are made tough and will not rust, freeze, or
otherwise "hang up" like old-fashioned pendulum styles. Like all of our manual instruments, each indicator is properly
dampened for smooth reliable readings. The 4120 model is designed for easy mounting with two screws, which allows for quick and efficient retrofitting in the field. The newest addition is the 4120-12v, a highly visible backlit model for increased safety - especially at night!
