Suitable for single bottom hinged windows with less than 1,5 m width.
To have less friction, in order to reduce the effort, a rope has substituted the helical cable which is present just in correspondence of the control operator.
Quick and easy installation. The conduit preparation tool is not required.
The small section of the conduit allows an only 50 mm radius bend: it is usually possible to install the conduit on the window frame.
Maximum opening 250 mm; the kit is provided with already cut spent travel tube.
The conduit, coated in PVC, is supplied in 3 m pieces.
NOTE: to open more than one window, loose elements must be ordered.
