OL Line

Flexible modular ventilation made easy

GEZE’s OL Line provides easy and reliable opening even for hard to reach windows. The system is modular, it consists of a manual opener fitted to the opening vent that is linked via lengths of conduit and cable to a wall mounted operator. 

Multiple vents can be operated easily from a single operator, and a variety of installation arrangements are available. 

Due to its modular design the OL Line is perfectly suited to retrofitting.
