Description
The Schneider Electric (Barber Colman) AM-392 Crank Arm is a mechanical linkage component designed to transmit rotary motion from an actuator to a damper shaft. The 3/4-inch sizing compatibility with standard damper shafts ensuring proper fit and effective motion transfer. It is used with MP-9000 series actuators to regulate damper position in air handling units and ventilation assemblies. Commonly fitted in duct control setups it provides mechanical coupling. In HVAC systems this arm supports accurate airflow adjustment, contributing to balanced air distribution and consistent operational control.
