LYRA BLOCK CREMONE

Cremones with a security lock for hinge side-hung or tilt & turn 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.
• In windows with tilt-before-turn operation, the cremone allows two locking positions to be achieved:
- 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.
• The reference does not include a polyamide transmission cover (ref. 0511193).
