Rieker Ball Bank Indicator reflect the operating procedures of Federal, State, and local roads and highways, based upon the “Speed Zone Theory” and “85th Percentile Speeds”, which is adapted by the American Association of State Highway and Transportation Officials (AASHTO); Institute of Transportation Engineers (ITE) and as defined in the Federal and/or State Manual of Uniform Traffic Control Devices, (MUTCD). Rieker indicators have been the ball bank standard instruments used by Federal and State Departments of Transportation Nationwide since the 1950’s.
Rieker manufactures mechanical inclinometers using precision glass tube and ball construction with engraved markings and customer specified color warning zones. All our tubes are filled with a proprietary damping fluid that controls the movement of the ball for a smooth and error free roll. The fluid combined with large, clear number and degree markings make it easy to get quick, accurate readings under a wide variety of severe environmental conditions.
