that includes the option(s).
Figure 2. Floor/Frame Mount Kit.
ASK71.11: For in-the-air stream
applications; anywhere a foot-mounted
actuator can be mounted. Can also be
directly mounted to a damper frame with
louvers and vents and in applications
where use of the floor mount is not
possible.
Kit contains:
Crank arm to change the angular
rotation into a linear stroke.
Support bearing ring to minimize
side loading on the actuator’s
output bearing.
Mounting bracket, and required
mounting fasteners.

Figure 3. Rotary to Linear Crank
Arm Kit.
ASK71.13: Allows a direct-coupled
actuator to provide an auxiliary linear
drive. Can be used to simultaneously
drive a set of opposing or adjacent
dampers with a single actuator. Kit
contains:
Crank arm to attach to the splined
hub of the shaft adapter.
Mounting fasteners.

Arm Kit with Mounting Bracket.
ASK71.14: Allows economical mounting
of an OpenAir actuator to a variety of
surfaces. Should be used in applications
where the actuator can be rigid-surface
mounted and a linear stroke output is
required.
Kit contains:
Crank arm to attach to the splined
hub of the shaft adapter.
Mounting bracket, and other
required mounting fasteners.

Figure 5. Tandem Mount
Bracket.
ASK73.3: Bracket provides an extended
anti-rotation pin allowing two actuators to
directly drive a single damper shaft
(tandem operation).
NOTE: GMA16x and GMA15x must not
be tandem mounted.
