OLIVARI has carried out a research on the issue of windows from the point of view of the users, who look for the quality and design of handles but also for security.
The DK by SECURITY is the outcome of this research. By blocking the handle’s rotation, it prevents the window from opening.
Anti-intrusion
The DK by SECURITY is a valid anti-intrusion system and it is always activated.
Any ill-intentioned person will not be able to turn the handle’s bar from the outside neither by making a hole at the handle’s frame nor by making a hole in the frame below the handle. The frame cannot, indeed, be turned from the outside since the security block blocks it.
Safe for children
Thanks to this system, it is more difficult for children to open the window. It is, in fact, necessary to press the button and rotate the handle at the same time.
Functional and noiseless
The application on the frame is very easy, like the action to be carried out is easy and instinctive: press the button to turn off the mechanism blocking the handle’s rotation.
The turning on of the DK from the locking position to the unlocking one is completely noiseless.
Suitable for all models
The system, which can be used with all OLIVARI models, is made of a particular internal mechanism that ends with a normal button on the DK plate. It does not interfere; it occupies a limited space and can be mounted both upwards and downwards.
The DK by SECURITY OLIVARI is a patented model .
