Details
ZG-JSLA+LF24-3 US Jackshaft Linkage with 35 lb-in Spring Return Actuator, 24 VAC/DC, Floating
On/off or floating control. Springs back to its fail-safe position on power loss.
The actuator is factory mounted on the linkage, vertical position only.
Torque at the jackshaft is lower than the actuator's rating; check the damper torque requirement before ordering.
Key Features
- Linkage jackshaft diameter: 1/2 to 3/4 in. with clamp insert; up to 1.05 in. with insert removed
- Direction of motion fail-safe: reversible with cw/ccw mounting
