Wind brace with corner transmission and a handle for a fully automatic locking and unlocking system.
Jeko is an inward opening system for single- or double-panel window frames; this innovative system by Esinplast is designed to make the air circulate gradually to ventilate the room by keeping the window ajar by 2 and 3 millimetres (micro-ventilation). Entirely concealed, it is not visible when the system is closed.
Jeko is an excellent alternative to tilt-and-turn windows, while it is also easier to install and less expensive, and can be used on frames of any weight.
