EN3300

Lockable shield with rotary knob EN3300 - similar to EN3000 without Vandalism function.

Anti-vandalism: If an abnormal force is applied or if a rough crank force is applied (> 45 Nm), the handle will slip. This feature prevents the door from being opened even if the outer shield looks no longer functional.

Restoring the external shield: return the handle to the correct position to return to its normal position, after unlocking, the door can be opened normally.
