Description

For use with Manual Window Controls It can only open bottom hinged windows which do not require pushing force for the opening.
Minimum size: the needed space for the installation is 20mm from the vent external limit.
Maximum opening stroke: 250mm; it can be adjusted for the end stroke spring placed in correspondence of the control operator.
For windows with a height inferior to 50cm it is necessary to reduce the stroke to 1/3 of the window height.
It is not necessary to work the conduit.
In systems with more windows it is necessary to use rotary junction boxes to transmit the cable movement from the main line to the auxiliary ones. For windows wider than 1.5m it is necessary to apply two or more thrust points.
