Applications

Minimum 270 in-lb Torque

For damper areas up to 66 sq-ft*

(For lower torque, see AFB, AF, NFB, LF, or TF series)

Mount directly to 1.05” jackshafts. (new ZG-120 bracket shown)

New standard clamp fits standard 1/2” shafts to 1.05” jackshafts. 

Linkage solutions are available when direct coupling is not possible.
