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. NEMA 3R Weather
Shield.
ASK75.3U: GMA actuators are UL listed
to meet NEMA 3R requirements (a
degree of protection against rain, sleet,

ASK75.7U: GMA Actuators are UL listed to
meet NEMA Type 4X requirements (a degree
of protection against falling dirt, rain, sleet,
snow, windblown dust, splashing water, hose-
directed water, corrosion, and damage from
external ice formation) when installed with an
ASK75.7U Weather Shield and outdoor-rated
conduit fittings. This weather shield may be
mounted in any orientation.
