LYRA BLOCK CREMONE

Cremone with handle locking device for hinged side-hung systems.

• The lock of the cremone handle is done by means of a key.
• The cremones can be used on side-hung windows by limiting the turn of the cremone to 90º.
• There are two locking positions for tilt-before-turn windows:
- Turning key 90º, the cremone allows to tilt but not to open the window.
- Turning key 180º, the cremone is blocked, preventing both opening and tilting the window.
