Sirius 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.

• 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.
