Figure 1. Floor Mount Kit.
ASK71.1U This kit allows foot mounting of the
actuators. This kit should be used for in-the-airstream
applications, and generally, anywhere a foot-mounted
actuator can be mounted.
This kit contains a crank arm that changes the angular
rotation into a linear stroke, a support bearing ring to
minimize side loading on the actuator’s output bearing,
a mounting bracket, and required mounting fasteners.

Figure 2. Frame Mount Kit.
ASK71.2U This kit allows mounting of the actuators
directly to a damper frame. This kit should be used with
louvers and vents and in applications where use of the
floor mount kit is not possible.
This kit contains a crank arm that changes the angular
rotation into a linear stroke, a support bearing ring to
minimize side loading on the actuator’s output bearing,
a mounting bracket, and required mounting fasteners.
Figure 3. Crank Arm Kit.
ASK71.3 This kit allows a direct coupled actuator to
provide an auxiliary linear drive. This crank arm kit can
be used to simultaneously drive a set of opposing or
adjacent dampers with a single actuator.
This kit includes a crank arm that attaches to the
splined hub of the shaft adapter, and other required
mounting fasteners.

ASK71.4 This kit allows economical mounting of an
actuator to a variety of surfaces. This kit should be
used in applications where the actuator can be rigidly
surface mounted and a linear stroke output is required.
This kit includes a crank arm that attaches to the
splined hub of the shaft adapter, a mounting bracket,
and other required mounting fasteners.
