The most popular lifter used for Awnings is the CM340.
The CM340 will cover some 80% of your awning installations with its lift height of 3.3 meters.
For installations on balconies, use the CM340 to lift the awning onto the balcony, then take the lifter onto the balcony to install the awning.
The CM520 will lift to 4.9 meters. This can give you a competative advantage - do the installations that others cannot.
