General information
Security device operation
VLSK. security lobe knob has been designed to prevent its unscrewing by unauthorised people. Therefore, it has got a vandal-proof function as well.
For clamping and unscrewing the knob, insert the special key into the lock and turn it by 180°. By so doing the clamping element and the knob form a single body. When the lock is brought back to the starting position and the key is removed, the knob turns freely preventing the unscrewing.
Features and applications
The particular design of the internal device and of the flange helps the drainage of any dirt (dust, earth or liquid).
