Description
Overview
The Schneider Electric (Barber Colman) AM-394 is a precision-engineered connecting link designed to mechanically couple actuators to damper or valve linkages in commercial HVAC control applications. Featuring two balljoints and an integrated turnbuckle, this link provides smooth, low-friction motion transfer while allowing for easy field adjustment to suit a wide range of installation geometries.
Adjustable Length for Flexible Installation
The AM-394 is adjustable from 15.75″ to 24.75″, giving technicians the flexibility to fine-tune the linkage length on-site without the need for additional hardware or custom fabrication. The turnbuckle design enables precise, tool-assisted length adjustment, ensuring accurate actuator-to-damper or actuator-to-valve positioning.
Dual Balljoint Design
Two balljoints — one at each end of the link — accommodate angular misalignment between the actuator and the driven component. This design reduces binding, minimizes mechanical stress on actuator shafts and valve stems, and extends the service life of connected components.
